Documentation/shortlog: scripted users should not rely on implicit HEAD
When passed no revision arguments, ‘git shortlog’ reads a log from
stdin if and only if stdin is not a tty. So scripts that need to
function identically when standard input is a terminal (as when run
interactively) and not (as when run through a cron job) should either
supply a log themselves or specify the desired revisions explicitly.

Additionally, "[PATCH]" will be stripped from the commit description.
+If no revisions are passed on the command line and either standard input
+is not a terminal or there is no current branch, 'git shortlog' will
+output a summary of the log read from standard input, without
