The repository dump must be piped out in binary mode on Windows, so I tweaked the tests do do that. And since I was already in that code, I made some cosmetic changes.

* subversion/tests/clients/cmdline/svntest/main.py (copy_repos): Quote
the path arguments to svnadmin dump/load, and open the dump streams in
binary mode. Use start-of-line and end-of-line matchers in the regular
expressions instead of explicitly matching \n. Prefix all error
messages to make them consistent with other error output. Break long
lines.
