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

[Christian Couder <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.
