 1.11  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.
 1.10  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".
 1.9  04-Apr-2025  rillig tests/make: demonstrate wrong error message for undefined variable

Found by wiz in pkgsrc/x11/gtk3.
 1.8  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.
 1.7  11-Jan-2025  rillig make: replace "Malformed conditional" with "Variable is undefined"

Evaluating a conditional such as ".if ${UNDEF}" produced a "Malformed
conditional" error, even though the form of the conditional was correct,
it was the content of the variable that was wrong.

Replace this message with the more accurate "Variable is undefined",
revealing which of the possibly many variables is actually undefined.
 1.6  10-Jan-2025  rillig tests/make: test expressions based on undefined variables

When an undefined variable is used in a conditional, make complains about
"Malformed conditional", which is wrong since the conditional is
well-formed but errors out during evaluation.

In order to fix this wrong error message and preserve the remaining
behavior, cover the places in which an expression is evaluated with
undefined expressions being an error (VARE_EVAL_DEFINED), but with
neither producing an error message nor handling errors. This combination
results in the same behavior as evaluating the expressions in the mode
that allows undefined variables to be used in expressions.
 1.5  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.
 1.4  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.
 1.3  15-Nov-2020  rillig make(1): add remarks to the tests about conditions
 1.2  20-Aug-2020  rillig make(1): add test for variable expressions 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.
