lynx-dev [PATCH 2.8.5-dev14] Cut&paste on unix

[Ilya Zakharevich]

This is slightly reworked patch to GNU readlien of mine.  If
RL_PASTE_CMD and RL_CLCOPY_CMD are defined in the environment, lynx
will use them as commands to do cut&paste.

The simplest such commands could just store/retrieve things from
/tmp/.clipboard_user-name; more advanced ones could use X clipboard.

Enjoy,
Ilya
