Fine, although this is such a minor issue that it doesn't seem worth your
time/skills. I'd rather see you tackle the really challenging stuff that
newbies and sporadic contributors could not manage, like the folding in the FEs
or PR52959 or the various bugs present in our macro unwinder (see point I at
https://gcc.gnu.org/wiki/Better_Diagnostics).

The last ones would require some discussion with Dodji about what result he
really wants to see. Perhaps this would be easier for you than for an outsider.
