Instead of direct docstring manipulation, how about an API to add
extension-specific "sections" to the docstring. This could result in
something like the following, without concerns that extensions would
interfere with each other.
hg push [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [DEST]
push changes to the specified destination
Push changesets from the local repository to the specified destination.
Returns 0 if push was successful, 1 if nothing to push.
pushrebase will enable "hg push" to automatically rebase pushed
changes on the server.
firefoxtree changes the behavior of pushes to Firefox repositories
so the default push revision is ".". This will prevent
attempted pushes of multiple heads, which would only get rejected
due to a server-side hook.
options ([+] can be repeated):
-f --force force push
-r --rev REV [+] a changeset intended to be included in the
