[ros-users] Yet another fix for vcstools + git

[Ken Conley]

Hi Peter,

I appreciate the description and patch -- it's best if you can just
attach these to the existing tickets, or open new tickets.  That way
you are setup to be notified by updates in the ticket, and it saves
the back-and-forth communication between e-mail lists and ticket
comments.

BTW: vcstools now has a new tracker now that it's been migrated to be
a standalone library, so if you want to file a new ticket (instead of
reopen 3251), the tracker is linked from the wiki page:
http://www.ros.org/wiki/vcstools

thanks,
Ken
