Pedro Alves June 4, 2019, 10:34 p.m. UTC 
  A following patch will introduce options for the "backtrace" command,
based on some "set print" and "set backtrace" settings.  There's one
setting in particular that is a bit annoying if we want to describe
the backtrace options and the settings commands using the same data
structures:

  "set print raw frame-arguments"

The problem is that space between "raw" and "frame-arguments".

Calling the option

  "bt -raw frame-arguments"

would be odd.  So I'm calling the option

  "bt -raw-frame-arguments"

instead.

And for consistency, this patch renames the set/show commands to:

 "set print raw-frame-arguments"
 "show print raw-frame-arguments"

I.e., dash instead of space.  The old commands are left in place, but
marked deprecated.

We need to adjust a couple testcases, because the relevant tests use
gdb_test_no_output and the old commands are no longer silent:

  (gdb) set print raw frame-arguments on
  Warning: command 'set print raw frame-arguments' is deprecated.
  Use 'set print raw-frame-arguments'.

gdb/ChangeLog:
yyyy-mm-dd  Pedro Alves  <palves@redhat.com>

	* NEWS (Changed commands): Mention set/show print raw-frame-arguments,
	and that "set/show print raw frame-arguments" are now deprecated.

	* cli/cli-decode.c (add_setshow_boolean_cmd): Now returns the
	command.
	* command.h (add_setshow_boolean_cmd): Return cmd_list_element *.
	* stack.c (_initialize_stack): Install "set/show print
	raw-frame-arguments", and deprecate "set/show print raw
	frame-arguments".
	* valprint.c (_initialize_valprint): Deprecate "set/show print
	raw".

gdb/doc/ChangeLog:
yyyy-mm-dd  Pedro Alves  <palves@redhat.com>

	* gdb.texinfo (Print Settings): Document "set/show print
	raw-frame-arguments" instead of "set/show print raw
	frame-arguments".

gdb/testsuite/ChangeLog:
yyyy-mm-dd  Pedro Alves  <palves@redhat.com>

	* gdb.guile/scm-frame-args.exp: Use "set print
	raw-frame-arguments" instead of "set print raw frame-arguments".
	* gdb.python/py-frame-args.exp: Likewise.
