Hello Francois
What happens is this:
- For cases where a terminal is missing a certain capability (for cursor
movement, clearing a line etc) rlwrap has a 'surrogate' routine to do the
same (e.g. printing lots of spaces to clear a line)
- There is an old and rather stupid bug in the surrogate 'clear line'
routine in rlwrap >= 0.30
- This has never been noticed because all current terminals have the
'delete line' capability (terminfo code 'dl1') so the surrogate was never
used
- Somehow, on newer Debian systems, xterm doesn't have the 'dl1'
capability anymore (or rather: tgetstr() doesn't find it) . This exposed the
bug in rlwrap
The bug is quite simple to fix (0-terminating strings is a *really* good
idea in C :-), but printing spaces to just clear a line is something I would
rather avoid (using such a system over a bad link will be unacceptably
slow)
So: why doesn't tgetstr('dl1', ...) find anything for your xterm?
Could you please run 'infocmp' inside an xterm and mail me the result?
Thanks again!
Hans
