I think numeric parameters are unambiguous when bundled.
I'm used to things like `diff -ru10p` working, *shrug*

Non-numeric parameters can only be used if the option is at the end of the
bundled string:

git commit -sam'this is my commit message'  would work

git commit -m'say hello' would also work

but git commit -mas'this is my commit message' would not work as intended
(where user wanted -a -s, too)

There are (currently) two types of abbreviations, one is the prefix one used
commonly in shell scripts:  -e|--e|--ed|--edi|--edit.  I think this should
always be supported as most of our shell scripts already do.

The other one tokenizes on '-' first and looks for a prefix match after
each '-'.  I'd like to make that at least optional:

diff --git a/gitopt.c b/gitopt.c
index 056e163..9ca6025 100644
--- a/gitopt.c
+++ b/gitopt.c
