If you have a directory named '~', I expect you are already used to
prefixing it with './' because '~' will be expanded in many places
where you might want to avoid.

Well. That's a bit extreme, I think if we add this then we handle case
by case in future when it makes sense, not blindly expanding '~'
everywhere.
The problem I have with this --template=~/path is tab-completion
actually completes the path, which (mis)leads me to think the command
will accept '~/' too. But this looks like a bug in git-completion.bash
though, it's a bit eager in completing stuff (or maybe it completes
"--template ~/path" and "--template=~/path" the same way).
I don't feel strongly about this. I'm OK with dropping these patches
if people think it's not a good idea (then I will try to fix
git-completion.bash not to complete '~' in this case).
