Subject: (job_next_command): Skip empty lines.
X-Git-Tag: 3.73.2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5d82479d89d0cce0359fa013e705059f6727676f;p=platform%2Fupstream%2Fmake.git

(job_next_command): Skip empty lines.
(new_job): Don't test the return of job_next_command.
Just let start_waiting_job handle the case of empty commands.
