[RFA] Merge fix for mingw support for Home,End,Insert and Delete keys inot gdb readline

["Pierre Muller" <pierre dot muller at ics-cnrs dot unistra dot fr>]

  This patch that I submitted in December last year
was integrated by Chet Ramey into the development branch of
the bash git repository.

  The patch below integrates this accepted patch into gdb readline.


OK to commit?
I am unsure about how to state inside the ChangeLog
that this patch is already inside the development branch of readline main
sources.




2013-09-24  Pierre Muller  <muller@sourceware.org>

	Merge patch accepted in bash development branch.
	* src/readline/readline.c (bind_arrow_keys_internal):
	Handle VK_HOME, VK_END, VK_DELETE and VK_INSERT for mingw
	hosts.
