test-lib.sh: set COLUMNS=80 for --verbose repeatability
Some tests will fail under --verbose because while we've unset COLUMNS
since b1d645b58ac (tests: unset COLUMNS inherited from environment,
2012-03-27), we also look for the columns with an ioctl(..,
TIOCGWINSZ, ...) on some platforms. By setting COLUMNS again we
preempt the TIOCGWINSZ lookup in pager.c's term_columns(), it'll take
COLUMNS over TIOCGWINSZ,
This fixes t0500-progress-display.sh., which broke because of a
combination of the this issue and the progress output reacting to the
column width since 545dc345ebd (progress: break too long progress bar
lines, 2019-04-12). The t5324-split-commit-graph.sh fails in a similar
manner due to progress output, see [1] for details.
The issue is not specific to progress.c, the diff code also checks
COLUMNS and some of its tests can be made to fail in a similar
manner[2], anything that invokes a pager is potentially affected.
See ea77e675e56 (Make "git help" react to window size correctly,
2005-12-18) and ad6c3739a33 (pager: find out the terminal width before
spawning the pager, 2012-02-12) for how the TIOCGWINSZ code ended up
in pager.c
