Re: [PATCH] git-web--browse: improve browser support under OS X

[Junio C Hamano <gitster@pobox.com>]

Because we preprocess git-web--browse.sh to create the final
git-web--browse to be installed, something like "open" that is
not a user but a platform preference might be better done as a
build-time thing, instead of forcing everybody to spawn "uname",
perhaps like this?

Also I wonder why the check for SECURITYSESSIONID your original
had is not good enough for this Mac specific customization?
