There are still cases where it is buggy:

# please also check http://pypi.debian.net/Flask-Mail/watch
version=3
opts="uversionmangle=s/(rc|a|b|c)/~$1/, dversionmangle=s/\+dfsg.*//" \
http://pypi.debian.net/Flask-Mail/Flask-Mail-(.+)\.(?:zip|tgz|tbz|txz|(?:tar\.(?:gz|bz2|xz)))

W: flask-mail source: debian-watch-file-should-mangle-version line 4

The warning goes away when I remove the space after the comma.

The version with the space is the syntax documented in uscan(1):

  Multiple options option1, option2, option3, ... can be set as
  opts="option1, option2, option3,  ...  " .
