[PATCH] Fetch: get the remote branches to merge from the branch properties.

[PATCH] Fetch: get the remote branches to merge from the branch properties.

[Santi Béjar]

If in branch "foo" and this in config:

[branch "foo"]
       merge=bar

"git fetch": fetch from the default repository and program the "bar"
             branch to be merged with pull.

Your patch has a very strange whitespace damage in it, and I am
not talking about quoted-printable encoding.

A tab in context before "When" is expanded into spaces, and the
empty line in the context does not have the leading SP.

I suspect you wanted to start the new line with a leading tab
before "When" but it is expanded into spaces here.

However, the diff for the other file in the same patch does not
have this problem.

No need to resend, as I hand-applied it to a new topic, but I am
a bit curious why one diff is broken when the other one is not
in the same e-mail message.

Last minute hand-editing, sorry. Did I already say it is very late here? :(

Just to comments (it's late here):

.- the branch.foo.merge must be the same as specified in the remotes/$remote.

.- I've already found a bug (it's late and I need to sleep, sorry).
This must only be done for the default repository (origin, or in
branch.foo.remote).
