less: Update version from 436 to 481

Peter Arndt needs a lesspipe feature. The script he means, is not
*lesspipe.sh* but a separate script shipped by Debian.

So, while at it, first update to the latest version, fixing several
bugs.

```
$ less --version
less 481 (POSIX regular expressions)

Change-log (for latest version) [1]:

> Less version 481
> ================
>
> Version 481 was released on 2 Sep 2015.
>
> These are the differences between version 458 and version 481:
>
> *   Don't overwrite history file; just append to it. This behaves better when multiple sessions are running less simultaneously and using the same history file.
> *   New command ESC-G goes to end of currently buffered data in a pipe.
> *   Disable history feature when compiled with LESSHISTFILE set to "-".
> *   In more-compatible mode, make the -p option apply to every file opened, not just the first one.
> *   In more-compatible mode, change the -e option to work like -E, not -EF.
> *   Treat multiple CRs before LF are like one CR (all the CRs are hidden).
> *   Allow "extra" string in lesskey file to append to a multi-char command (like a search pattern), without executing the command.
> *   Ignore -u/-U setting while viewing help file, so that underline and bold chars are displayed correctly.
> *   Improve detection of "binary" files in UTF-8 mode.
> *   Fix bug with ++ commands.
> *   Fix bug where prompt was sometimes not displayed with +G.
> *   Fix possible memory corruption
> *   Fix bugs and improve performance in ampersand filtering.
> *   Allow %% escape sequence in LESSOPEN variable.
> *   Automate construction of Unicode tables from Unicode database.
