Indeed! I actually had started with something very similar, and
backtracked, because other units failed to compile. But that was
because I had also made the return value a "const" which, in
hindsight, was no reason for me to backtrack the whole way!

Attached is what I ended up pushing.

gdb/ChangeLog:

        * cli/cli-utils.h (extract_arg_const): Add declaration.
        * cli/cli-utils.c (extract_arg_const): New function.
        (extract_arg): Reimplement using extract_arg_const.

Tested on x86_64-linux.

Thanks, Pedro.
