One of examples that have been only rarely fixed was for_each_ref
forcing callers to using static variable to store gathered data
instead of passing the data as one of arguments.

I'm a bit used to "push", "fetch" and "pull". I consider "pull"
a bit of artifact from times of one branch per repository layout.
The fact that "pull" fetches _all_ the branches but merges one
[usually] with the _current_ branch (unless you configure it other
way)...
I'll leave "push" as is, leave "fetch" as is, and make "pull" to be
"fetch" by default unless you use "--merge[=<branch>]" option.
I'd rename "merge" to "merge-driver" and make new "merge" thanks
to new users wouldn't have to learn to use "git pull . branchA"
to merge current branch with branchA.
Perhaps would make it possible to specify remote branch a la cogito,
<URL>#<branch>, to pull remote branch without tracking branch, and
for symmetry have "--pull[=<repo>]" or "--fetch[=<repo>]" option.

Very nice idea, but one must remember the limitations of import/export tools
and of course limitations of other SCM... well, and also limitations of
Git, if there are any compared to other SCM ;-)
