Bug#789389: /usr/bin/uscan: [uscan] manpage suggests incorrect syntax for dversionmangle

[Martin Erik Werner]

Package: devscripts
Version: 2.15.5
Severity: minor
File: /usr/bin/uscan

The section on dversionmangle in the manpage:

dversionmangle=rules
       This is used to mangle the Debian  version  number  of  the  currently
       installed package in the same way as the uversionmangle option.  Thus,
       a suitable rule might be `s/+dfsg\d*$//' to remove a  `+dfsg1'  suffix
       from the Debian version number, or to handle `.pre6' type version num‐
       bers.  Again, the rules string may not contain commas; this should not
       be a problem.

Suggests using `s/+dfsg\d*$//' as the rule, however, using this results in:

uscan: In debian/watch, potentially unsafe or malformed dversionmangle pattern:
  's/+dfsg\d*$//' found. Skipping watchline

It should instead be `s/\+dfsg\d*$//', escaping the '+'.
