[PATCH] _git-checkout: Reorder default completions.

[-- Attachment #1: Type: text/plain, Size: 188 bytes --]

A quick series to change the order of alternatives in 'git checkout
<TAB>'.  I realize it's somewhat of a bikeshed, but on the other hand,
I'd like to have good defaults.

Cheers,

Daniel

Subject: [PATCH 2/2] _git-checkout: Reorder default completions.

The unprefixed name of a remote branch is used to create a new local
remote-tracking branch; that is presumed to be a rarer operation than
either switching among local branches or reverting to the index version
of a modified file.

Between the remaining two, put modified files before tree-ishes because
there are generally few of the former and many of the latter.
