First letter shall be uppercase.  Two spaces after period, before
beginning a new sentence.  The date must also be updated if/when you
commit.

Same formatting issues here in this comment: two spaces after period.

I know almost nothing about this part of the code, but as far as I have
seen, the patch looks OK.  I am not a maintainer, however.
