Patch registers SIGTSTP hook where it sends reset terminal color control sequence using write and fsync. Handler is installed only if signal is not 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

This is an updated and extended version of the original patch: https://www.redhat.com/archives/libguestfs/2010-August/msg00163.html This adds OCaml and Perl bindings (both tested), support for progress bars in virt-resize, and adds progress notifications to a number of the simpler commands. Still to do is to add progress messages to more commands. There are still a few commands which would be
