This limit applies on my Windows XP box. AFAIK, this limit is actually
in the win32 api, where relative paths are limited to 255 but absolute
paths are not. e.g. opening a file

I have a Real Life(tm) repository that has very long path names.
To demostrate, in Windows:
1) create a directory structure that is very deep. e.g. more than 255
characters. One way of doing this is using cygwin (while true; do mkdir
test; cd test; done). As cygwin suffers from the same problem, it will
stop when the 255 char limit is exceeded.
2) Create a file (echo "hello" > afile) in the deepest directory.
3) Then import into a repository.
4) Check out the repository into a new directory called 'path'. Notice
the difference between the two checkouts:
a) svn co svn://repos c:\path
and
(from the parent directory of path)
b) svn co svn://repos path
(a) should succeed and (b) should fail, assuming that the instructions
are correct.
