Andrew Burgess a15a5258b5 gdb: update command completion for watch, awatch, and rwatch
Switch over to using new option processing mechanism for watch,
awatch, and rwatch commands.  Add command completion function.

This means that expression completion now works correctly when the
-location flag is used.  So previously:

  (gdb) watch var.<TAB><TAB>
  .... list fields of var ....

But,

  (gdb) watch -location var.<TAB><TAB>
  .... list all symbols ....

After this commit only the fields of 'var' are listed even when
'-location' is passed.

Another benefit of this change is that '-location' will now complete.

One thing to note is that previous these commands accepted both
'-location' or '-l' (these being synonyms).  The new option scheme
doesn't really allow for official short form flags, however, it does
allow for non-ambiguous sub-strings to be used.  What this means is
that currently (as these commands only have the '-location' flag) the
user can still use '-l', so there's no change there.

The interactive help text for these commands now emphasises
'-location' as the real option, but does mention that '-l' can also be
used.

gdb/ChangeLog:

	* breakpoint.c (struct watch_options): New struct.
	(watch_option_defs): New static global.
	(make_watch_options_def_group): New function.
	(watch_maybe_just_location): Convert option parsing.
	(watch_command_completer): New function.
	(_initialize_breakpoint): Build help text using options mechanism.

gdb/testsuite/ChangeLog:

	* gdb.base/completion.exp: Add new completion tests.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
