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". Signed-off-by: Romain Francoise <romain@xxxxxxxxxxxxx> --- 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.
