Post Hooks Broken!!! Fix Attached.

[Steven Johnson <sjohnson@neurizon.net>]

Hi,

I Tried to use a late CVS snapshot of GDB/Insight and found my Post Hook
was broken.

It seems that it has been broken since the CLI sub-directory was
created, it was a simple problem and the patch to fix it is attached. 
Defining a Post-Hook currently overwrites the standard pre command hook,
In the definition code, I had to fix the setting of the pointers to the
hook code which were erroneously setting the pre pointers instead of the
post pointers.

Steven.
