log tests: check if grep_config() is called by "log"-like cmds

avar · gitster · commit ff37a60c3695 · 2022-02-15T18:00:49.000-08:00
Extend the tests added in my 9df4676 (log: add exhaustive tests for pattern style options & config, 2017-05-20) to check not only whether "git log" handles "grep.patternType", but also "git show" etc. It's sufficient to check whether we match a "fixed" or a "basic" regex here to see if these codepaths correctly invoked grep_config(). We don't need to check the details of their regular expression matching as the "log" test does.
