* app.c (do_scrub_next_char): Added new state, 9, to avoid

Browse source 
dropping a space immediately following an identifier.
	* expr.c, write.c: Rewrote assert expressions to not use multiple
	lines; I don't think that can be done portably.
	* config/tc-mips.c (macro): Use $AT if target register is zero in
	load instruction, which it can be for a floating point load.

Also a bunch more changes to config/obj-ecoff.c, still in flux.

/* I added state 9 because the MIPS ECOFF assembler uses constructs
like ``.loc 1 20''. This was turning into ``.loc 120''. State 9
ensures that a space is never dropped immediately following a
character which could appear in a identifier. It is still
dropped following a comma, so this has no effect for most
assemblers. I hope. Ian Taylor, ian@cygnus.com. */
