git-shortlog.txt: make SYNOPSIS match log, update OPTIONS

There are broadly two problems with the current SYNOPSIS.  First, it
completely omits the detail that paths can be specified.  Second, it
attempts to list all the options: this is futile as, in addition to
the options unique to it, it accepts all the options that git-rev-list
accepts.  In fixing these problems, make the SYNOPSIS consistent with
that in git-log.txt.  Also add the corresponding sections to OPTIONS.
Save adding the options from rev-list-options.txt for a later patch,
as it requires some work to pick out the options that are relevant to
shortlog.

+       specifies all the commits reachable from the current commit

+Paths may need to be prefixed with "\-- " to separate them from
+options or the revision range, when confusion arises.
