 1.22  28-Jun-2025  rillig make: consistently use double quotes in error messages

Previously, some error messages used single quotes, very few used
backticks or parentheses, most already used double quotes.

While here, reword a few error messages to be clearer or more consistent
with related error messages.
 1.21  04-Apr-2025  rillig make: fix error message for undefined variable in conditional

Previously, only ${UNDEF} had the proper error message, while
${UNDEF:M*} still produced the wrong "Malformed conditional".
 1.20  30-Mar-2025  rillig make: use '"filename" line 123' for locations instead of 'filename:123'

The format 'filename:123' is commonly used for identifying a location in
a file. Text editors recognize it and allow quick navigation through it.
The previous format was specific to make and would have required custom
support in editors.

The new format was already used in stack traces, except for the first
line. Now all lines use the same format.
 1.19  29-Mar-2025  rillig make: add ":" to error message about unknown modifier

In the manual page, the modifiers are listed with a preceding ":", so
use the same pattern in the error message. This removes an inconsistency
between the error messages "Unknown modifier" and "Bad modifier".
 1.18  11-Jan-2025  rillig make: omit redundant follow-up message "Malformed conditional"

If there is a parse error or an evaluation error during the conditional,
the conditional is already mentioned in the "while evaluating condition"
line, so there's no reason to repeat it once again.

Same for the "Bad condition" message from the '?:' modifier.
 1.17  29-Aug-2024  rillig make: reduce line length in error messages

The error messages for deeply nested parse errors were hard to decipher,
due to the large amount of text. Split these messages into individual
lines, just as in the backtrace for .include files and .for loops. This
unified backtrace makes the output more uniform.
 1.16  06-Aug-2024  rillig make: in error message about conditionals, use single quotes

Single quotes are used less often in the conditionals themselves, which
leads to fewer confusions.
 1.15  05-Jul-2024  rillig make: in error messages for anonymous variables, log the value
 1.14  04-Jul-2024  rillig make: on error, print the targets to be made

This helps to understand situations with several nested sub-makes in
varying directories.
 1.13  04-Jul-2024  rillig make: add more context information to error messages

In case of a parse error or evaluation error, print the variable value
in addition to the variable name, to see the effects of previous
expression modifiers.

In nested make calls, print the current directory at the bottom of a
stack trace, as that information is otherwise hard to get in a parallel
build spanning multiple directories.
 1.12  20-Apr-2024  rillig branches: 1.12.2;
make: provide more context information for parse/evaluate errors
 1.11  17-Dec-2023  rillig tests/make: extend tests for include guards and empty expressions
 1.10  01-Jun-2023  rillig tests/make: force line-based diagnostics to be listed in the tests

This way, contradictions between the intended output and the actual
output are closer together and have a better chance of being spotted.
 1.9  23-Feb-2021  rillig make: improve error message for unknown modifier

Back in 1995, the modifiers were all single-character, and it made sense
to print only the first character. Nowadays, with ':S', ':@var@...@',
'::=' and several others, a little more context is useful to see where
the exact error is. The actual modifier is still guessed, and the guess
may be wrong as soon as backslashes get involved, but it is still better
than before.
 1.8  23-Feb-2021  rillig make: add context information to error message about ':range' modifier
 1.7  21-Dec-2020  rillig make(1): remove excess newline from parse errors (since 2020-11-01)

For the modifiers :gmtime and :localtime, the excess newline had been
added in var.c 1.631 from 2020-10-31 21:40:20.

For the modifiers :range and :ts, the excess newline had been added in
var.c 1.635 from 2020-11-01 14:36:25.
 1.6  20-Dec-2020  rillig make(1): error out on unknown variable modifiers at parse time

Before, make printed an "error message" that did not include the word
error and thus was not easily identified as such. This "error message"
also did not influence the exit status in the default mode but only in
-dL mode. The error message also didn't include any line number
information and was thus rude.
 1.5  01-Nov-2020  rillig make(1): treat malformed :range, :ts and :[...] as errors

Before, integer overflow in the :[1..2] modifier had not been detected,
and the actual behavior varied between ILP64 and LP64I32 machines.

Before, the :ts modifier accepted character literals like \012345 and
\x1F600, which don't fit in a single character and were thus truncated.

Before, the :range modifier issued an "Unknown modifier" error message
for :range=x, which was not quite correct. The error message in this
case is now "Invalid number".
 1.4  01-Nov-2020  rillig make(1): add tests for the variable modifiers :[words] and :range
 1.3  01-Nov-2020  rillig make(1): add more tests for the variable modifier :range, edge cases
 1.2  23-Aug-2020  rillig make(1): move tests for :hash :range :localtime into separate files
 1.1  16-Aug-2020  rillig make(1): add dummies for fine-grained tests, one per single feature

The test names have been derived from the current manual page.

All these tests are dummies right now, and the code from the existing
tests will be moved into the new tests step by step.

This is done to prevent modmisc, escape, varmod-edge and varmisc from
growing without any bounds, and to reduce the side-effects of one test
to the others.
