>Description:
file-pr creates a list of email addresses to notify using
the Resent-CC mail header. There's a bug that makes it fail
separating the addresses with a comma. This can lead to a
new mail beeing sent to gnats-admin, which generates a new
report. This new mail is in turn generating a new report,
a we have an endless loop!

The try_append_notify function doesn't use the returned
char*, but uses its input argument.

>How-To-Repeat:
Here's what I had in my categories file:
test:*Test Category:girgen:girgen@e.kth.se

and submitters:
submitters:partitur:Partitur:none:24:gnats-admin:palle@partitur.se

and here's the mail header:

Resent-CC: gnats-adminpalle@partitur.segirgen@e.kth.se

I realize this code in file-pr is quite modified in the
current cvs-tree, but this patch should probably be used
until that code is in the 3.x branch.
