Re: [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".

The motivation for this is that I want the viewer to be "woman" in
Emacs shell buffers and "man" otherwise, and having an environment
variable (like PAGER or EDITOR) is cleaner than using a
man.viewer.cmd wrapper to do the redirection.

Obviously I am biased, as I am among the people who have PAGER=cat and
EDITOR=emacsclient, and 70% of whose command invocation is from within the
"M-x compile", but I like this.
