[arch-dev-public] [signoff] less-436-1

[Allan McRae]

Upstream update

These are the differences between version 429 and version 436:
   * Don't pass "-" to non-pipe LESSOPEN unless it starts with "-".
   * Allow a fraction as the argument to the -# (--shift) option.
   * Fix highlight bug when underlined/overstruck text matches at end 
of line.
   * Fix non-regex searches with ctrl-R.
Signoff both.
