Copies and history

[Joe Drew <ho...@woot.net>]

[I might have sent this to users@, but I can't seem to get mail through
to that list.]

Consider the situation:
1. Create a file, creating revision n-1.
2. Change it, creating revision n.
3. Copy it to another name, creating revision n+1.

Now try to get the diff from revision (n-1):n on the new copy. (svn:
'svn+ssh://capricorn.woot.net/var/subversion/cs350_090/test2' was not
found in the repository at either revision 73 or 74)

svn log lists the complete history, but I can't get the diffs between
them. This seriously limits the utility of tags.

This is a known bug (can't recall the issue number) and we've had
tons of discussion this past week about solving exactly this.

Until then, do your diffs like so:

   svn diff /url/before/the/tag@n-1 /url/after/the/tag@n
