[RFA] Deprecation fixes

[dan at cgsoftware dot com (Daniel Berlin+list.gdb-patches)]

This patch fixes a crash if you call "maintenance deprecate" with no
arguments.
I also added the prototype to make the warnings about it being
implicitly declared go away, and removed the unknown escape sequences
caused by spaces where they shouldn't be.

Fernando, can i check it in?
