- change special markers in text_to_html from \x001 and \x002 to \u0002 (start of text) and \u0003 (end of text). The previous coding did not work always reliably, regsub was missing some entries, probably due to a mess-up of the internal representation.
- fixing a probably old bug: changed the markers in ad_text_to_html since the old markers with the funy camel case led to problems (at least with current regexp implementations) in the text below, only 5 of the 8 urls were correctly transformed into anchor markup. The new markers uses uniqe single char starting and ending marker, marking also regexp much simpler. - the function is further generalized (unifying http/https/ftp urls with mailto urls) and probably faster
A welcome contribution would be e.g. an extension of the api-browser for callbacks (listing contracts/implementations, etc.).
