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.
Since nothing has come along in over 4 1/2 years that's wanted to use it, it's more valuable to make it consistent with "grep" 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>.
