Xin LI f0be0a1f8c Update less to v436. This is considered as a bugfix release from vendor.
Major changes from v429:
 * 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.
