There is an escaped pipe character, because this ends up in a Markdown table
on the wiki, and the wiki software (incorrectly, I think) sees the pipe inside
a code-block and thinks it's the end of the table cell if not escaped.
But this escape char looks wrong everywhere else.
Keeping the parameter table terse is always a good idea, so I moved the
detail out to the Remarks section, which doesn't have a problem with this
character appearing in the text.
