[Fwd: [patch] Fix doco for ``!'' and ``R'' packets]

[Andrew Cagney]

FYI,

When comming up with this patch I was grubbing around and trying to 
understand gdbserver (gdbserver is at present the nearest thing we have 
to a reference implementation of the protocol).

The thing I noticed was that, the ``!'' packet tells the remote server 
to _NOT_ exit.  I know of one gdb server implementation that uses 
options to control this, the options are not needed and ``!'' should 
probably be used instead.

The only thing to fix (per TODO) is to merge ``remote'' and 
``extended-remote'' and try to use what was refered to as 
extended-remote by default.
