RFA: Ugly "show user" output revisited

In September I submitted a proposed patch to fix the "show user" output.
(Command verbs like "if" and "while" are displayed twice.) I got
involved in another project and let that patch fall on the floor. Here
is a new variation of that patch with an associated testsuite change
that I would like for you to consider. -- Jackie

gdb/ChangeLog:

2001-12-13  Jackie Smith Cashion  <jsmith@redhat.com>

	* cli/cli-script.c (print_command_lines): Remove extra
	"if", "else", "while", and "end" from show user output.


testsuite/ChangeLog:

2001-12-13  Jackie Smith Cashion  <jsmith@redhat.com>

	* gdb.base/commands.exp (user_defined_command_test): Make "show user"
test
	expect string more specific.
