Extend the tests added in my 9df46763ef1 (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 a PCRE regex matches for the purposes
of this test, we otherwise assume that it's running the same code as
"git log", whose behavior is tested more exhaustively by test added in
9df46763ef1e.
