Subject: Regenerate deps.mk: read the comments once

mkwb grew a commentsdata action that reads every comment there is into
one corpus, and a comments -d that reads the corpus rather than the
sources.  The pages wait on the corpus now; the corpus waits on the
sources and on src/global.json, which it is read from.

src/comments.data is built, so .gitignore takes it and clean removes
it.  The rendered site is unchanged.
