Subject: notmuch-emacs-mua: set EMACS{,CLIENT} variables to defaults when empty
X-Git-Url: http://rtime.felk.cvut.cz/gitweb/notmuch.git/commitdiff_plain/e870d73dc8830fbfc4c79b02c839ced0d42f73a5

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.
