 * Rewrite Latex#escape_latex method, so it uses only one pass (avoids some
   escape-the-already-escaped-characters problems and it's probably faster)
 * Now backslashes are substituted by "\synbs{}", to avoid problems with letters
   that could be just after the \synbs, turning it into another, undefined
   command like "\synbsn" or something
