	* tests/tlsIO.test: updated comments, fixed a pcCrash case that
	was due to debug assertion in Windows SSL.

	* tls.c (ImportObjCmd): removed unnecessary use of 'bio' arg.
	(Tls_Init): check return value of SSL_library_init.  Also lots of
	whitespace cleanup (more like Tcl Eng style guide), but not all
	code was cleaned up.

	* tlsBIO.c: minor whitespace cleanup

# Running socket tests with a remote server:

# Some tests in socket.test depend on the existence of a remote server to
# which they connect. The remote server must be an instance of tcltest and it
# must run the script found in the file "remote.tcl" in this directory. You
