[Patch]: chdir

["Pierre A. Humblet" <pierre at phumblet dot no-ip dot org>]

Here is a simple patch that simplifies chdir processing
and avoids calling normalized_posix_path multiple times.

If it doesn't break anything it will simplify removing
trailing dots and spaces, as discussed earlier today.

I have kept the test "pcheck_case == PCHECK_RELAXED",
although I don't see why it helps. Also I have not edited
the long comment on line 3329. I don't understand all the
points it is trying to make. I think the patch does what
the FIXME talks about, except that it's actually cheap.

During tests I have seen that 'touch "    "' touches the
current directory. It's probably a good idea to disallow
names consisting entirely of spaces, as we already disallow
names consisting entirely of dots.

	* path.cc (chdir): Do not check for trailing spaces.
	Specify PC_POSIX in constructing "path". Pass normalized_path to 
	cygheap->cwd.set except when it starts with a drive.
	(cwdstuff::set): Assume posix_cwd is already normalized.
