It's a nit, but please don't use accents for quoting, that hurts my eyes. Your
options:
- ‘proper’ typographic quotes (bad, because they're non-ASCII characters and
will confuse some compilers even in comments)
- 'regular' ASCII quote/apostrophe replacement characters
- the Chromium convention of |pipes| around identifiers in comments.

Done.
