minor cleanups to update_current_target

Browse Source 
During the conversion I kept all the "do not inherit" comments in
update_current_target.  However, now they are not needed.  This patch
updates the comments for INHERIT and de_fault, and removes the
somewhat odd INHERIT of to_stratum.

2014-02-19  Tom Tromey  <tromey@redhat.com>

	* target.c (update_current_target): Update comments.  Do not
	INHERIT to_stratum.
