That would work as well, assuming path names have not changed since rev 5.

-r only references the state of the file as it was in rev x. The name
lookup is still done in the HEAD revision by default, and once the file
is found, it is backtracked to rev x. Peg revisions cause the lookup to
be done in rev y rather than HEAD. The result is that if you need to
reference a path as it existed in a given rev, you must use a peg
revision to refer to the file with the old name. If you want to refer
to the file with its new name ( if any ) then you need to use -r. If
the name has not changed, then either way is acceptable.

No, you don't have to be explicit, HEAD is used by default, so a simple
svn checkout url-to-foo will check out the HEAD revision.
