[PATCH] gdb/doc: Fix incorrect use of @xref.

[Andrew Burgess <andrew dot burgess at embecosm dot com>]

It has been pointed out to me that in commit a4ea0946c I introduced a
use of @xref that is not followed by either a ',' or a '.' as it is
supposed to be[1].

Normally I would push such a trivial change as an obvious fix,
however, I'm a little more nervous when it comes to documentation
changes, so I'd like a review please.

Thanks,
Andrew

All uses of @xref must be followed by either '.' or ','.  In commit
a4ea0946c an incorrect use of @xref was introduced.  This commit
switches to using @ref in order to avoid the need for '.' or ','.

gdb/ChangeLog:

	* doc/gdb.texinfo (TUI): Switch use of @xref to @ref.
