Hmm, it says that 'second commit' is not a valid tag name ;-) Okay, I can work around it by making the commit message "second".

On another note though, I think I need to add a "test_tick" for the commit just below as well:

        echo "original $dollar" >afile &&
        git add afile &&c
        git commit -m "do not clobber $dollar signs"

So, here's the re-rolled patch.

Since efb779f (merge, pull: add '--(no-)log' command line option,
2008-04-06) git-pull supported the (--no-)log switch and would pass it
to git-merge.

96e9420 (merge: Make '--log' an integer option for number of shortlog
entries, 2010-09-08) implemented support for the --log=<n> switch, which
would explicitly set the number of shortlog entries. However, git-pull
does not recognize this option, and will instead pass it to git-fetch,
leading to "unknown option" errors.

Fix this by matching --log=* in addition to --log and --no-log.

Implement a test for this use case.
