Last I looked at this, I decided not to change anything because I simply
couldn't figure out what is the syntax of comments in BibTeX.
I've found various textual descriptions, but they're all vague, and from my
tests against the actual implementation, they didn't seem to correspond to
any actual truth.

So please explain clearly what's the syntax of comments in BibTeX:
for both % and @comment, the two questions are
- where can they appear?
- where does the comment end?
