how optparse can go horribly wrong

*sigh*.  Someone just ran into this today:

  $ git commit -a -ammend
  [work ce38944] mend
   1 files changed, 2 insertions(+), 0 deletions(-)

Omit one - and include an extra 'm', and instead of --amend you have -a -m mend. Which isn't exactly what you wanted.

We do catch -amend with an error though:

  $ git commit -amend
  error: did you mean `--amend` (with two dashes ?)

I wonder, should the -m flag on commit not allow cuddling its value against the switch when its combined in short form with other switches?
