What was mangled?

I think this line may be problematic:

Is your intent really to replace “ awk” and “|awk”?  In my previous
patch I tried to more explicit by using alternatives in the group:

> +               (("(\"|`|\| )awk" _ prefix)

Was there a problem with the version above?  It does not replace “ awk”
and “|awk” but only “| awk” (in addition to the other two variants).

Other than that the patch does look fine.  If you confirm that this is
what you intended then I’ll push it as is.

Thanks!
