/*
** Output Wiki text while inserting the proper HTML control codes.
** The following formatting conventions are implemented:
**
** * Characters with special meaning to HTML are escaped.
**
** * Blank lines results in a paragraph break.
**
** * Paragraphs where the first line is indented by two or more
** spaces are shown verbatim. None of the following rules apply
** to verbatim text.
**
** * Lines beginning with "*: " begin a bullet in a bullet list.
**
** * Lines beginning with "1: " begin an item in an enumerated list.
**
** * Paragraphs beginning with "_: " are indented.
**
** * Multiple colons can be used in *:, 1:, and _: for multiple
** levels of indentation.
**
** * Text within _..._ is italic and text in *...* is bold.
** Text with in **...** or ***...*** bold with a larger font.
**
** * Wiki pages names (Words in initial caps) are enclosed in an
** appropriate hyperlink.
**
** * Words that begin with "http:", "https:", "ftp:", or "mailto:"
** are enclosed in an appropriate hyperlink.
**
** * Text of the form "#NNN" where NNN is a valid ticket number
** is converted into a hyperlink to the corresponding ticket.
**
** * Text of the form "[NNN]" where NNN is a valid check-in number
** becomes a hyperlink to the checkin.
**
** * {quote: XYZ} renders XYZ with all special meanings for XYZ escaped.
**
** * {link: URL TEXT} renders TEXT with a link to URL. URL can be
** relative.
**
** * {linebreak} renders a linebreak.
**
** * {image: URL ALT} renders an in-line image from URL. URL can be
** relative or it can be the name of an attachment to zPageId.
** {leftimage: URL ALT} and {rightimage: URL ALT} create wrap-around
** images at the left or right margin.
**
** * {clear} skips down the page far enough to clear any wrap-around
** images.
**
** * Text between <html>...</html> is interpreted as HTML. A restricted
** subset of tags are supported - things like forms and javascript are
** intentionally excluded. The initial <html> must occur at the
** beginning of a paragraph.
