Subject: [PATCH 1/2] config api: Add git_config_magic_int()

From: Andreas Ericsson <[email-masked]>
Date: Tue, 12 Feb 2008 09:21:21 +0100

There are some values where git can reasonably guess at an
optimal value. For such occasions, this is a nifty addendum
to the config api, letting the caller specify a magic string
and a magic setting to return if the value of the variable
matches the magic string.

An example would be for threads, where 0 = auto is overly
voodoo-ish for some consumers, and typing "auto" is much
nicer and more immediately obvious.
