Hello
I was working with the Readline library on a linux basic shell and i
found some unexpected behaviour with the unix_line_discard,
kill_backward_line and kill_full_line functions. The program i am writing
has a signal handler for ctrl+c and the purpose of it would be to "clear"
the previous input considering that everything behind the ctrl+c is
redundant.
If you try to call readline functions from a signal handler, in the middle
of readline handling the signal itsef, all bets are off. You can't reliably
do anything from a signal handler except set variables or call a small set
of signal-safe functions.
