text: Title: Keystroke ] not detected on Windows
  Body: In Powershell and cmd.exe I encountered that sorting didn't work in both orders. The `[` shortcut was detected and had its effect, but the `]` didn't. I narrowed it down to a problem with `windows-curses`, and in turn with its dependency `PDCurses`: https://github.com/zephyrproject-rtos/windows-curses/issues/41
  
  Here's my plan on how to address it. I hope I'll get around to it somewhere next week.
  - [ ] Improve the mapping in `PDCurses` and submit a pull request
  - [ ] Bump the git submodule in `windows-curses` to the `PDCurses` version that has the fix and ask/wait for a release of this package
  - [ ] Address the issue in this repository, perhaps by pinning `windows-curses` to a version of at least the newly released package.
  
  I'm making this issue here just to document it and track progress. If you're reading this because you have this issue, I would recommend using WSL instead. (WSL is not an option for me unfortunately).
  
  I didn't include the `.vd`-file to reproduce this issue. The simplest way to reproduce it is to get a Windows computer, run `visidata` from Powershell or cmd.exe and sort any column by pressing `]`.
