* | win32: add support for virtual terminal inputRon Yorston2023-03-051-9/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alter certain applets to support virtual terminal input, if enabled. In many places this is achieved by building previously excluded upstream terminal-handling code. The busybox-w32 implementation of termios(3) functions does nothing if virtual terminal input is disabled, so it can be invoked regardless. Some applet-specific terminal-handling code is also required. This affects less, more, vi and command line editing in the shell. (The `more` applet isn't enabled in the default configuration.) This series of patches adds about 1.7KB to the binaries.
