Hum, so `git mw preview origin:page.mw` would just do the get
request to the remote mediawiki, save it locally and - maybe - load it
in the browser ? Is it really better than just opening the browser and
typing the right URL ?
Currently, this URL is one click away when you have preview file loaded
in a web browser.

ok, thanks a lot.

The fact is, `git symbolic-ref HEAD` result would have to be parsed in order
to extract the current branch name like I currently extract the remote name.
So, is it really better than `git rev-parse --symbolic-full-name @{upstream}` ?

Well, I thought that `git mw preview` could provide an interactive mode
where, if the first search fails, it would find all the mediawiki remotes, and
offers to the user a way to choose the remote ?
