Subject: notmuch-emacs-mua: set EMACS{,CLIENT} variables to defaults when empty
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=e870d73dc8830fbfc4c79b02c839ced0d42f73a5;p=notmuch.git

notmuch-emacs-mua: set EMACS{,CLIENT} variables to defaults when empty

... in addition to doing this when these variables are unset.

It is more useful to use defaults (emacs or emacsclient) than empty
string as a command name.
