In the situation given (file modified between revisions 5 and 10, and we
want to get what it was in revision 5), you only need "svn co -r5
url-to-foo", which is equivalent to "svn co -r5 url-to-foo@HEAD", and
which means "checkout the file currently named foo that existed in
revision 5". The syntax given by Mr. Heppenstall (svn checkout
<URL>@5..." is wrong; it's full equivalent is "svn co -rHEAD <URL>@5",
which means "checkout the current revision of the file that was at this
URL at revision 5".
The only time you really need to specify both a -r argument and a peg
revision is when a file has been (potentially) deleted or moved, and you
know what its name was at some point in the past. Your original
understanding was correct.
