close#8074
I attempted to refactor the "input" command. The reason for this is that
the current implementation of the "input" command lacks consistency for
different options. For instance, some parts use `std::io::stdin` while
others use `crossterm::event::read`.
In this pull request, I have made changes to use crossterm consistently:
- Detection of the -u option is now done using `crossterm`'s
`KeyCode::Char`.
- The current input is displayed when using `crossterm` for input (it
won't be displayed when -s is present).
- Ctrl-C triggers SIGINT.
# User-Facing Changes
Users can interrupt "input" with ctrl-c.
this PR should close#9018
# Description
This PR aims to fix the `input` command with `--suppress-output` on
Windows
This fixes two separates issues :
- Keypresses being duplicated in output due to "Release" event not being
ignored
- "Return" event from entering the `input -s "blah :"` still being in
the event buffer (need to be cleared before reading keypresses)
