[PATCH v2 3/7] log: add -P as a synonym for --perl-regexp

Add a short -P option as a synonym for the longer --perl-regexp, for consistency with the options the corresponding grep invocations accept.

This was intentionally omitted in commit 727b6fc3ed ("log --grep: accept --basic-regexp and --perl-regexp", 2012-10-03) for unspecified future use.

Make it consistent with "grep" rather than to keep it open for future use, and to avoid the confusion of -P meaning different things for grep & log, as is the case with the -G option.

As noted in the aforementioned commit the --basic-regexp option can't have a corresponding -G argument, as the log command already uses that for -G<regex>.
