 1.25  06-Jul-2025  rillig make: complain about unfinished escape sequences or string literals
 1.24  06-Jul-2025  rillig tests/make: demonstrate missing error for unfinished word in condition
 1.23  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.
 1.22  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.
 1.21  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.
 1.20  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.
 1.19  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.
 1.18  14-Feb-2023  rillig make: don't interpret the return value of Var_Parse

The return value of Var_Parse is largely redundant to the returned
string. The idea behind the type VarParseResult was to migrate all call
sites to checking this return value instead of the returned string, but
that hasn't happened. Instead, the additional type only added more
complexity.

There was a single place where that return value was actually used, when
parsing conditions. And even in that case, ignoring the VarParseResult
added back an error message that previously hid bugs, in the test
cond-token-plain.mk.

Even though these error messages are redundant in the other tests, they
don't hurt as they don't happen often.
 1.17  25-Sep-2022  rillig tests/make: reduce trailing whitespace
 1.16  03-Mar-2022  rillig make: make debug logging for comparisons less technical
 1.15  08-Jan-2022  rillig make: fix reported line numbers of continuation lines (since 2002)

Previously, multi-line directives like '.info' or '.error' reported the
line number of their last line instead of their first line, which is
more usual. This also affected the debug log from '-dp'.
 1.14  30-Dec-2021  rillig tests/make: demonstrate edge case that evaluates an expression twice
 1.13  12-Dec-2021  rillig tests/make: refine comments for parsing and evaluating conditions
 1.12  21-Sep-2021  rillig make: do not allow unquoted 'left == right' after modifier ':?'

Having a static variable for state that clearly belongs in the parser
looked suspicious, and indeed it was wrong.

When the distinction between .if conditions and expressions of the form
${condition:?:} was added in cond.c 1.68 from 2015-05-05, a new unit
test was added, but it didn't cover this edge case. At that time, the
state of the condition parser consisted of a few global variables
instead of a separate data type, as would have been appropriate for
parsing nested conditions.
 1.11  21-Sep-2021  rillig tests/make: demonstrate unintended unquoted string in conditions
 1.10  21-Jun-2021  rillig make: fix grammar in error message for malformed conditional
 1.9  21-Jan-2021  rillig make(1): replace warning + error with just an error in conditionals

Before, there was a "warning" for comparing strings using '<', which was
wrong. That warning was then followed by an error, after parsing the
whole conditional. This was only because it was easier to implement.

Replace the warning with an actual error. This only affects
conditionals in .if lines, the conditionals in the :? modifier such as
${"A" < "B":?smaller:greater} still print 2 errors.
 1.8  21-Jan-2021  rillig make(1): fix debug output for comparison operators in conditionals

This produces fewer warnings than before, but these were edge cases that
probably didn't matter in practice. The "Malformaed conditional" is
still generated, the set of accepted conditionals is still the same.
 1.7  21-Jan-2021  rillig make(1): demonstrate parse error without error message in conditional
 1.6  21-Jan-2021  rillig make(1): add test case for bare word containing quotes
 1.5  21-Jan-2021  rillig make(1): add more tests for edge cases in conditionals
 1.4  21-Jan-2021  rillig make(1): add more tests for tokens in conditionals
 1.3  12-Sep-2020  rillig make(1): add tests for comparison tokens without whitespace
 1.2  11-Sep-2020  rillig make(1): add tests for really strange edge cases in conditions
 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.
