no wrap/inst involved - i just updated the file concerned (in my
private copy of acme).  if you make the change in /sys/src/cmd/acme,
you should be aware that subsequent installs will detect that it's
changed, will warn you, and won't update the file.

i guess it should probably be a proper update, but i haven't got the
time now.

basically, edit /sys/src/cmd/acme/ecmd.c.  change the printposn
function to look like this:

printposn(Text *t, int charsonly)
{
	long l1, l2;

	if (t != nil && t->file != nil && t->file->name != nil)
		warning(nil, "%.*S:", t->file->nname, t->file->name);
	if(!charsonly){
		l1 = 1+nlcount(t, 0, addr.r.q0);
		l2 = l1+nlcount(t, addr.r.q0, addr.r.q1);
		/* check if addr ends with '\n' */
		if(addr.r.q1>0 && addr.r.q1>addr.r.q0 && textreadc(t, addr.r.q1-1)=='\n')
			--l2;
		warning(nil, "%lud", l1);
		if(l2 != l1)
			warning(nil, ",%lud", l2);
		warning(nil, "\n");
		return;
	}
	warning(nil, "#%d", addr.r.q0);
	if(addr.r.q1 != addr.r.q0)
		warning(nil, ",#%d", addr.r.q1);
	warning(nil, "\n");
}


this change makes the acme Edit = commands print fully qualified acme
addresses, which seems to make more sense... (it also means that you
can use them to mark a current position in the file, etc)

  cheers,
    rog.
