 1.10  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.
 1.9  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.
 1.8  05-Jul-2024  rillig make: in error messages for anonymous variables, log the value
 1.7  30-Jun-2024  rillig make: add detailed exit status to message for failed sub-commands

Several commands communicate via the exit status and not only
distinguish between zero and non-zero, so make this information
available to ease investigations.

The command "false" is not guaranteed to exit with a consistent status,
so use "(exit 13)" instead in the tests, to keep these tests portable
across different operating systems. The exit status 127 is required for
a shell that cannot find a command, so keep that one.
 1.6  30-Jun-2024  rillig make: add more context to "returned non-zero status" message

Previously, this message was an "error" but had no influence on the exit
status, so make it a warning instead. In the seldom used -W mode that
treats warnings as errors, this change influences the exit status.
 1.5  26-Mar-2022  rillig branches: 1.5.4;
make: avoid trailing whitespace in debug log for variables

Since trailing whitespace is invisible, describe the variable value in
words to make it visible.
 1.4  10-Jan-2022  rillig make: add debug logging for capturing the output of external commands

This applies to all 4 situations in which the output of an external
command is used for modifying a variable or an expression:

* the assignment operator '!='
* the assignment modifier '::!='
* the SUN shell modifier ':sh'
* the other shell modifier ':!cmd!'

Previously, only the shell modifier ':!cmd!' had debug logging.

Suggested by Christoph Badura.
 1.3  17-Nov-2020  rillig make(1): fix error message of failed :!cmd! modifier (since 2000-04-29)
 1.2  17-Nov-2020  rillig make(1): document 20-year-old bug in the :!cmd! modifier
 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.
 1.5.4.1  01-Jul-2024  perseant Sync with HEAD.
