[PATCH 0/5] More fixes to less

[Ron Yorston]

This patch series supersedes two of my recent patches to less that
haven't been committed.  It also adds a whole lot more.

The overall bloat introduced by the series is:

function                                             old     new   delta
update_num_lines                                       -     127    +127
