gas macro arguments or escapes botched, perhaps related to ONLY_STANDARD_ESCAPES

The problem is not an invalid testcase.  ONLY_STANDARD_ESCAPES was
defined in MIPS as well, but I removed it since it does more harm than
good.  If you want to use an argument name in an ascii string inside a
macro you have to use an argument name that gives you a standard
escape sequence:

.macro narg1
	.ascii "\narg1"

Instead of how you normally would write it:

.macro arg1
       .ascii "\arg1"

I think the problem has been in gas for years.  Feel free to fix it.
