Error: unterminated character constant: '

I get the following error while trying to build rust:

If there's more info I need to provide just let me know.

maybe this commit 4989a56 was too eager to promote a normal comment to a doc comment?

very weird, I saw this same problem when doing a make install from scratch, but then a repeated run in the same build tree did not reproduce the problem; so one might need to be working from a clean tree to reproduce.

the issue I noted above is due to #15555
