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>.
