Redmine

Changesets/Issues association already exists, but can not be
edited manually. Here how it works (in the latest source code).
You use keywords in your commit messages to reference or even
close issues automatically (redmine scans commit comments when
adding changesets in the database). These keywords are defined
in Admin -> Settings.

Look at this example:
http://demo.redmine.org/issues/show/1

You can see the reference to a changeset (on the right of the
issue description).
This is automatically done since the commit message of changeset
5 is:
"Slight modifications (refs #1, #3)"
(refs is one of the default keywords used to reference issue
ids in commit comments).
When looking at the changeset 5, you can see the 2 referenced
issues.

Would you also like to be able to manually edit this Changesets/Issues
assoication in Redmine ?

Thanks for pointing this out -- this is a different
implementation than I had in mind, but it gives me exactly
the functionality I wanted! The User Manual doesn't seem
to have any info on using svn, so I didn't know about this.

I've marked this issue as "Closed" - sorry if I'm not
supposed to do that.

I know, user documentation is not really up to date :(
