  - Yet another brown-paper bag release.  I seem to like doing these.
  - Fix regression where I free a pointer that should not have been freed due
    to a variable renaming that wasn't completed. (Daniel Li / Landon Bourma)
  - Put back, in a modified form, HTML href directory path fixing that was
    removed in 2.1.2. If the "baseHREF" part after the -H begins with a dash
    (-), the dash is removed and the lead directory name is removed from the
    href, otherwise it is left as-is.  It can be very difficult to know how to
    handle the host and directory part given the plethora of protocols and
    what-not, so hopefully this should give enough control over that to suit
    most requirements.
