I'm just upstreaming http://bugs.darcs.net/issue1513

It seems that if you use the roundup-admin interface to 'set
issueXXX,issueYYY nosy=+foo', this has the effect of applying the same
exact nosy list to both issues, and not the intended effect of
separately appending the user foo to both nosy lists.

Luckily, roundup made it very easy to automatically correct this
(nice!), but this sort of thing might bite others in the future.

Yup this is true. Can be replicated in demo.py interface.

The code is in in roundup/admin.py:do_set() looks like
it may be the culprit.

I'll take this and see if I can figure out what's happening.

I am going to up this to major since it can cause incorrect data
that can be recovered from but ..

Thanks for the report.

Found and squashed the bug. A variable needed to be reinitialized every
time though a loop.

The first time through the loop the var had the value +foo.
Then it was evaluated to add the foo user to nosy and
the value was changed to exact value demo,foo (assuming demo
was the original nosy value for the first item designator). Then the
exact value got used to set the rest of the designators.

By resetting the variable to +foo for every designator it magically
works the way it was intended.
