Rewrite cli-style.c:do_show

Rewrite cli-style.c:do_show

IMO it looks a little nicer if cli-style.c:do_show uses a single
printf to display its output.  This is also slightly more
i18-friendly.

I noticed this while debugging a case where multiple redundant ANSI
escapes were sent.  In conjunction with a subsequent patch, this
approach happens to fix that problem.  FWIW I don't consider such
redundancies to be bugs, but it was convenient to change this one.
