From 5059a427804f9fefaf75dd1aa92cb620ce9219c7 Mon Sep 17 00:00:00 2001 From: Romain Francoise Date: Fri, 29 Aug 2008 17:00:43 +0200 Subject: [PATCH] builtin-help: fallback to GIT_MAN_VIEWER before man In some situations it is useful to be able to switch viewers via the environment, e.g. in Emacs shell buffers. So check the GIT_MAN_VIEWER environment variable and try it before falling back to "man".
