Fixed a problem reported by Nick Ing-Simmons: p4 -s print sticks an extra linefeed in after every 4097 (or maybe 4098, I didn't check too closely) bytes, cause all p4->foo transfers to break.

Not sure if that's a bug in p4 or expected behavior, but it does mean that vcp now does a plain ol' "p4 print //depot/foo#5" and trims off the header line (if it's present).

There's a new "a_big_file" in the test suite to test against this, so we shouldn't see that problem again.

Nick also raise the C++ API, and I mentioned to him that someone had done an XS wrapper around it for Perl, is that in use anywhere? Does it work on Windows?
