Various buglets fixed (from submitter):

	The changes to getstr() is so that the character that is
	passed in to it, is also processed just as the rest. I also
	removed one of the getc() calls otherwise you loose every
	second character.

	I also changed the strcpy of kname, so that it only happens if
	kname is '\0'. This is so that one can pass a kernel in
	through /boot.config.

	The last change to boot2.c is in parse(). If you tried to type
	a kernel name to boot, the first character was lost, the arg--
	fix that.
