lynx-dev refresh_screen & first document

[Leonid Pauzner]

There is a strange old bug really annoying on my system
(Linux, 1.9.9e curses), it is found only in Advanced user_mode
and only when Lynx started on localfile like "lynx ." or "lynx -book".

Visual effect: when the page loaded I got the screen messed near the bottom:
statusline became duplicated and when I scroll with pageUP/pageDown later
I got garbage near each end-of-line positions _from_ previous page
(exactly: those characters from the first page that was not overriden
from the last document).
And this garbage still live for all the later documents
until I force Cntrl-W to refresh the screen (reload Cntrl-R will not help).

That is really strange - it is found only for localfiles and never for HTTP.

Cntrl-W code looks as simple as follows:

        case LYK_REFRESH:
           refresh_screen = TRUE;
           lynx_force_repaint();
           break;

Probably configure definitions may be useful:
