Re: [PATCH 1/2] Allow '-' in config variable names

Linus Torvalds [off-list ref] writes:

I need this in order to allow aliases of the same form as "ls-tree", 
"rev-parse" etc, so that I can use

	[alias]
		my-cat=--paginate cat-file -p

to add a "git my-cat" command.

I do not have problem with this (and would perhaps also want to
add '_' to keychar set), but people who envisioned parsing
config from scripts (i.e. Perly git) might prefer if we stayed
within alnum, since I'd suspect then they may be able to reuse
existing .ini parsers.  I do not much care about that myself,
but I am bringing it up just in case other people might.

Other than that, this sounds nice.

By the way, everybody seems to do "alias.xxx = -p cat-file -p"
(I have it as "git less").  Maybe we would want to make a
built-in alias for that?
