[PATCH] git-help: fix looking up html install dir when browsing.

From: Christian Couder <chriscool@tuxfamily.org>
Date: Dec 7, 2007, 05:29 UTC
Message-ID: <20071207062923.6663a7d1.chriscool@tuxfamily.org>

We used to search for the following directories:

	- $PREFIX/share/doc/git-doc
	- $PREFIX/share/doc/git-core-$GIT_VERSION

This was wrong because "htmldir" could be defined in the Makefiles to something completely different.

So we now look for the $htlmdir directory first. But if it fails we still fall back to the two above directories, in case the script install and the html doc install have been done with different $htmldir.

	This should fix it.
	Thanks.
