I don't think it will handle the case where h2, h3, and  h4 are all used
in the text, but the sequence h2, h4 occurs.  To put it another way,
the problem of checking whether headers are in a legal sequence is
context sensitive, while a regular-expression search and replace (even
if the replacement sequence remaps the targets) is context-free.
