Need clarification on possible bug with start on / stop on stanza logic

[Garrett Cooper]

Hi Scott and other Upstart devs,
    I found this gem while producing tests for upstart, and I'm
wondering whether or not this is a bug that should be filed:

[comet-k5-12:/etc/init/jobs.d]$ cat foo+
stop on halloween / duwali
[comet-k5-12:/etc/init/jobs.d]$ start foo+
[comet-k5-12:/etc/init/jobs.d]$ start foo+
start: Unable to start job: Job is already running: foo+

    My thoughts are that characters like words (jobnames, event names,
etc), (, ), spaces, and simple boolean operators (and, or) are valid,
but other characters like '/' and invalid expressions should not be
parsed.
    Comments welcome.
Thanks,
-Garrett
