Seems like it.  :-)  I guess I wasn't that clear, but the actual code
that initialy bothered me was the clearing the *ignore* counts in
generic_mourn_inferior, or better, the comment there that I must have read a
hundred times already by now, although it's dead code.

Just curious, do people think that it's useful to clear the hit
count automatically at all, considering that we do it on "run" but not
on "attach" or "target remote"?  I can't seem to make up my mind
on it.  It's still logicaly the same breakpoint across runs, so it
could make sense to not do so.

Right, that would mean storing a hit count per-breakpoint location as well
as per-breakpoint, it seems.  Same for ignore counts.  I'm sure there's
a user out there who would find that useful for breakpoints with multiple
locations in the single-inferior case too.  :-)
