fish doesn't complete custom git commands

[xdudi]

Fish should seach executable files like: git-command and complete its by tab.
For example, i have: /usr/local/bin/git-history
When i type: git histo<TAB>, it should complete it.

Bash makes it correctly.

Bash does this by scraping the output of git help:

git help -a|egrep '^  [a-zA-Z0-9]'

Looks like that picks up all git commands, not just custom commands. Custom commands "git foo" can be completed by completing the name "git-foo" instead, which is all git does to find them anyway.

The benefit of bash's approach is it will pick up new builtin git commands as well, though the downside is it will expose them by default, whereas the current git bash completion actually blacklists a lot of commands (e.g. plumbing commands).
