We're not consistently quoting when there's just a single word, see
in particular spec_ctrl_asm.h. And thinking about it again I also
don't see why we would want or need to enforce quotation when none
is needed. Therefore both here and in patch 2 I'll keep (or make,
when I touch a line anyway) things consistently unquoted where no
quotes are needed. Please let me know if your R-b holds without the
requested adjustment.
