Subject: test: set EMACS_SERVER variable only after dtach(1) was successfully started
X-Git-Tag: 0.11_rc1~93
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=9d5b521472d1ac401ca2667d1261b641bef208cb;p=notmuch.git

test: set EMACS_SERVER variable only after dtach(1) was successfully started

Otherwise, we can set the EMACS_SERVER and return with an error.  And
subsequent calls to test_emacs would assume that emacs server is running.
