using git_config_bool_or_int, as I am hoping a future version will use
a third value (maybe -1) to
indicate JIT will be tried first, but then the interpreter will be
used in case JIT is not available (as
recommended in PCRE)

not sure also about the right name and where to document this flag, as
this is not only restricted to
the grep subcommand and the issue it is working around will be also
relevant for log (including pickaxe)
