Bug#276345: copy-paste troubles with the first line of a less

[Loïc Minier <lool@dooz.org>]

Package: xterm
Version: 4.3.0.dfsg.1-8
Severity: normal

     Hi,

 It's been some months now that I repeatedly get a strange problem with
 a less in xterm:  if I select the first line of the xterm window, being
 the first line of the less dump too, I am pasting some sort of buffered
 data too, coming from previous lines of output.

 Say I have done a "grep -r foo bar | less", and copy-paste the first
 line of the xterm ("bar/xyz.c: ..."), I get what I've selected plus
 some preprended text ("blahblahbar/xyz.c: ...").  This happens when I
 select one or multiple lines or one or multiple words including the
 upper left word in the less in xterm.  It DOESN'T happen when I select
 character-wise (single-clicking instead of double- or triple-clicking).

 I can't reproduce deterministically but once I get it, it always happen
 with the same display.  Restarting the less usually clears things up.

 I think I already got the problem with vim a while ago, but I'm not
 copy-pasting so much from vim, either to it.

 I believe it's a but in the copy-paste word selection of xterm wich
 doesn't check if the characters selected are displayed and goes out of
 bound, but I can believe it is caused by improper terminal handling by
 less.
