I noticed what used to be commentary for search_buffer slowly drifted
away from the function it was describing.

I brought the two together again, updating the commentary to reflect the
function's current interface.

In the process I noticed the RE argument to search_buffer and
search_command was always used as a boolean flag, so changed its type
accordingly.

WDYT?

Thanks,
