Many callers of setup_revisions() do so only to run two-thing diffs
(e.g. run_diff_files() that compares the index and the working tree),
but some do so to traverse the history with the grep_filter
(e.g. "git log --grep=<pattern>").  "git log -P" may affect how that
pattern is used to match the contents of the log messages, no?
