Barosl Lee c7fa52df34 Prevent /**/ from being parsed as a doc comment
Previously, `/**/` was incorrectly regarded as a doc comment because it
starts with `/**` and ends with `*/`. However, this caused an ICE
because some code assumed that the length of a doc comment is at least
5. This commit adds an additional check to `is_block_doc_comment` that
tests the length of the input.

Fixes #28844.
