This allows you to force git to avoid symlinks for refs. Just add
something like

	[core]
		symrefsonly = true

to .git/config.

Donīt forget to "git checkout your_branch", or it does not do anything...

	Linus, is there any reason you donīt allow spaces, underscores
	and dashes in the config variables?

	Petr, happy?
