J.T.

Have you considered what to do when there is a choice of software
breakpoints?
Jim Ingham's pointed out to me that in the case of the MIPS/MIPS16 and
ARM/THUMB the breakpoint might be 2 bytes or 4 bytes in size (and the
value different in each case).

For such targets, always sending the length would be easiest.  Can any
one see problems with sending the length regardless?
