The logic is in fact quite far from common. While at it, stop accounting "---p" mappings as mapped (e.g. VSZ in top).

2025-08-03docs: Add links to cmd description from cmd listNoelle Leigh2-7/+14
In the generated `docs/busybox.pod` file, add a link for each command in the big command list that goes to that command's description, like a compact table of contents. This seems to only affect the generated HTML version of the usage page. To add `id` attributes to each usage section title, each command now uses `=head2` instead of `=item` for their section heading. To add links to each command in the list, the list was unindented so that it could use rich text, and each command was marked as code text (C<>) so they are styled in monospace. These changes mean that the HTML and mandoc command list will expand to fit the available width of the viewport, rather than wrapping at a fixed line-length. The plain text version retains its existing wrapping behavior. Because of the new code text formatting, `--quotes=none` was added to the pod2man and pod2text invocations in Makefile.custom to prevent the command list from quoting every single command.

2025-07-30crond: reap orphaned grandchildren to prevent zombie buildupValentin Lab1-0/+4
If a cron job launches a background task, e.g. `sh -c "sleep 5 &"`, the shell exits immediately and the `sleep` process is re-parented to PID 1. When BusyBox `crond` itself happens to be PID 1 (common in a minimal container), those orphans become direct children of `crond`. Because `crond` only calls waitpid() for the PIDs it explicitly tracks, these processes remain forever in Z state and the container slowly fills with zombies. Add a small `while (waitpid(-1, NULL, WNOHANG) > 0)` sweep at the end of check_completions() so any stray children are reaped. When `crond` is not PID 1 the loop returns -ECHILD immediately, so behaviour and overhead on a normal system are unchanged.
