rsync handler fails when trying to include paths with spaces

first, thank you for backupninja and such a useful set of handlers. i've been using it for years with only minor issues.

however, i am now bumping into a problem with the rsync handler when i try to set: include = /srv/share/Videos/TV Shows the rsync backend incorrectly splits this into attempts to backup //srv/share/Videos/TV/ and /Shows/ (debug output below). i've tried quotes and backslashes to no better effect.

please let me know if there is any additional information that would be useful.

thanks again!
