- set `MAN_KEEP_FORMATTING=1` and `MANPAGER=cat` for the man
command and handle overstriking in the terminal emulation.
- this approach works on macOS, linux, FreeBSD and OpenBSD
- apply infinite-height prior to winsize initialization.
- use `LESS_LINES` environment variable.
- use `PAGER=less -F` to make less quit at the end of the man page
The behavior follows this priority order:
1. reuse an existing window already displaying the buffer,
2. if shell-command-other-window is not set, use the current
window, otherwise
3. select the largest available non-active window.
4. split a new window if no sutiable window is found.
5. fall back to the current window if splitting fails.
- `shell_buffer_read_only` controls if the shell buffer should become
read-only and use pager-mode when not interactive
- `shell_mode_auto_interactive` controls if the shell interactive mode is
switched to and from automatically based on cursor movement commands
- disable auto interactive if region is highlighted
- fix crash bug in qe_register_emulation_bindings for "emacs" emulation
* decouple interactive mode from cursor position.
* clear readonly when entering interactive mode and
restore when leaving it.
* simplify navigation logic by removing offset-based toggling.
* set pager mode on interactive shell exit.
* check for active processes in shell buffers before reusing them,
and prompt the user to kill the running process to avoid leaving
it detached and unreachable.
fixes a race condition where pty data was lost on process exit.
The pid callback now flags the exit status, while `shell_read_cb`
handles the final teardown. This prevents truncation for
high-throughput processes.
