 1.23  30-Mar-2025  rillig make: let the ":t" modifiers fall back to the ":from=to" modifier

Suggested by https://bugs.freebsd.org/285726.

This means that the ":t" modifiers cannot have future extensions that
include a "=", as that may break existing code.
 1.22  29-Mar-2025  rillig tests/make: remove copy-and-paste errors from warning messages

Several of the warnings didn't match what they actually tested, so
remove them all to prevent further disagreements.
 1.21  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.
 1.20  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.
 1.19  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.
 1.18  05-Jul-2024  rillig make: in error messages for anonymous variables, log the value
 1.17  04-Jul-2024  rillig make: error out on the "Bad modifier" error message

Previously, the "Bad modifier" error message did not affect make's exit
status. As a side effect, this kind of error now gets more context
information.
 1.16  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.
 1.15  01-Jun-2024  rillig tests/make: test more modifiers and special variables
 1.14  20-Apr-2024  rillig make: provide more context information for parse/evaluate errors
 1.13  19-Nov-2023  rillig tests/make: replace 'variable expression' with 'expression'

Each expression is based on a variable, there's no need for the
verbosity. The wording in make's diagnostics will be changed in a
follow-up commit.
 1.12  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.
 1.11  09-Feb-2022  rillig make: fix mistakes, spelling and typos in comments and manual page

No binary change for -DNDEBUG.
 1.10  23-Jan-2022  rillig tests/make: add a few more tests
 1.9  23-Jan-2022  rillig tests/make: add more tests for the modifier ':ts'
 1.8  23-Jan-2022  rillig tests/make: migrate modts to varmod-to-separator and explain
 1.7  15-Nov-2020  rillig make(1): update and add comments in tests

As a result of the new comments, some line numbers have changed in the
output of the tests. No other changes.
 1.6  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".
 1.5  01-Nov-2020  rillig make(1): add tests for parsing errors in the :ts variable modifier
 1.4  01-Nov-2020  rillig make(1): add test for out-of-bounds separator in variable modifier :ts
 1.3  31-Aug-2020  rillig make(1): move some of the :ts tests into a separate file

The successful cases can be easily tested in the .if conditions. Around
these conditions, there is enough space for explaining the test cases
and their purpose.

The failure cases have been left in the file for now since they still
produce unwanted characters in the output. These characters are not
produced when the parse error occurs in a conditional.
 1.2  16-Aug-2020  rillig make(1): describe the purpose of each newly added unit test dummy
 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.
