 *
 * Takes $string, and wraps it on a per-word boundary (does not clip
 * words UNLESS the word is more than $cols long), no more than $cols per
 * line. Allows for optional prefix string for each line. (Was written to
 * easily format replies to e-mails, prefixing each line with "> ".
 *
 * Puts words that do not fit at the end of the line to the 
 * beginning of the next line (keeping in mind prefixes) and not on a line
 * by themselves.
 *
 * parameter $string 		-- text to be wrapped
 * parameter $cols  		-- maximum width of text
 * parameter $quote_old 	-- adds the prefix for each line if true
 * parameter $prefix 		-- prefix used in message (nice_prefix but w/o spaces)
 * parameter $nice_prefix	-- prefix that is easier to read (i.e. "> " instead of ">").
 *
 * $nice_prefix is actually written to the message (if $quote_old), but $prefix is used for 
 * backward compatibility
 * 
 * Please note that though quote_old may be false, prefix and nice_prefix are still used to maintain
 * the existing structure of a message (in case the message is a reply or etc...)
