As documented, the history library is used to split the previous
history entry into words, and ESC-. fetches the last word, as if the
!$ expansion had been used.
Since `#' is the history comment character, there's no last word for
the history expansion code to fetch. The bell signals the expected
lack of output.
Not that odd the ^R, which moves between history entries, behaves one
way, and ESC-. and ESC-#, which history expand the previous entry,
behave another.
