* representations using a line "folding" technique. That is, a long
* line can be split between any two characters by inserting a CRLF
* immediately followed by a single linear white space character (i.e.,
* SPACE, US-ASCII decimal 32 or HTAB, US-ASCII decimal 9). Any sequence
* of CRLF followed immediately by a single linear white space character
* is ignored (i.e., removed) when processing the content type.
*
* Edited 2007-08-26 by Anders Litzell, anders@litzell.se to fix bug where
* the reserved expression "\n" in the arg $string could be broken up by the
* folding of lines, causing ambiguity in the return string.
* Fix uses var $breakAtChar=75 and breaks the line at $breakAtChar-1 if need be.
