[PATCH] fish: reset the console on ^Z RHBZ#1213844
...ot being ignored.
Patch uses rl_free_line_state and rl_cleanup_after_signal to unhook
readline from terminal, then it calls original TSTP handler using
approach in URL below and again hooks readline using
rl_reset_after_signal.
Handling is based on code from:
http://man7.org/tlpi/code/online/dist/pgsjc/handling_SIGTSTP.c.html
This approach seems to mostly work. User is sometimes able to get
readline into state when it doesn't correctly respond to newline.
^Z and subsequent fg helps there as reset command helps broken
terminal. I haven't noticed this using previous approach copied from vi...
