None of these are a big deal, and Michal said he's working on libifying
this anyhow:

- making 'fill' a special operation is weird
- anchor the key regex to beginning of line (not strictly necessary)
- sort the output tokens (after 'url' is extracted) so the output is consistent and testable

Yup.  But what you call "read" and "write" are, to the credential
helper, "write" and "read" but it's the same protocol :)  So maybe the
names should be changed to reflect that, e.g. "query" and "response."

I don't know--it's up to the `git-remote-mediawiki' maintainers...  But
I think anywhere you have Git, you also have Git.pm, right?  Maybe?  But
then you also have to look at whether Git.pm has the functionality you
need... so I better go quiet :)
