Hi,
This series adds support for custom merge strategies.
The first 3 patches modify builtin-help to allow using it from other
builtins. This is necessary because in the error message of 'git merge
-s foobar' we show something like 'git help -a', but we list only merge
strategies. A command is considered a merge strategy if it has a
git-merge- prefix and is listed in the all_strategy array or it is
somewhere in PATH, but outside `git --exec-path`, so that git-merge-ours
and other strategies are shown, git-merge-index and other
git-merge-named (but not strategy) commands are hidden.
The last two is about removing those problematic 'git-merge-index',
'git-merge-tree' and other bogus commands from the output of 'git merge
-s foobar'. I think the benefit of doing it that way is that we don't
have to maintain a list of commands which are named git-merge-foo but
not strategies _and_ the custom strategies can have a form of
git-merge-foo, without adding extra complexity (like forcing users to
name them git-merge-custom-foo).
NOTE: At the moment the custom strategies are named as git-merge-foo as
well, mainly because I think it's not that problematic to exclude the
already existing git-merge-fo non-strategy commands, but this can be
changed to git-merge-strategy-foo if we really want so.
Also, I'm aware that this is a feature and we are in rc freeze, I just
did not want to keep back this series till 1.6.0 is out.
