- Use a POSIX-compliant/portable extended regular expression to match on word-boundaries, rather than guessing which regex library `bash` was linked against. See https://stackoverflow.com/a/12696899/555333 for explanation and code suggestion.
Rewrite comment on disabling the `DEBUG` trap in subshells, which is now handled upstream as of rcaloras/bash-preexec#26.
Alsö, fix the guard variable assignment to allow it to be overridden elsewhere (e.g., for testing).
Define the helper functions for `bash-preexec.sh` immediately after importing it, rather than in `lib/theme`.
- `__check_precmd_conflict()` and `save_append_prompt_command()` are generally useful and not theme-specific.
- Add matching `__check_preexec_conflict()` and `safe_append_preexec()`.
