Description

Hi

I've discussed this issue with Ben on IRC and he asked me to go ahead and raise
an issue.

I wondered what would happen if you set the svn:externals property on a
directory so that it pointed to its parent directory. So:

http://localhost/svn/recurse/recurseme has the svn:externals value
"http://localhost/svn/recurse".

I also created two files, "file1" and "file2" in recurse/

The answer is exactly what you'd expect:  when a checkout is issued, the client
merrily recurses round the tree creating ever deeper and deeper nested
directories until this happens:

"svn: Can't open file 'recurse/recurseme/...<lots of lines of
/recurseme/recurseme>.../recurseme/.svn/text-base/file1.svn-base': File name too
long"

I realise this is user error rather than an actual bug, but Ben thought svn
might be able to trap this situation.
