  • mto: This revision was merged to the branch mainline in revision 6245.
  • Revision ID: wence@gmx.li-20111108105409-cgdqeek7vl7e8nbb
Only set check_clean if {clean} is asked for in template
      
The {clean} flag in templates requires an lstat of every file in the
repository.  If the filesystem is slow this can take a noticeable
amount of time.  So only switch check_clean to True if the template
actually asks for it, to avoid penalising those who don't want to
know.
