I saw this but didn't really have enough interest in answering,
if the completer really wanted to check with specific ps options, it could
use zstyle to check the current context for the command style, if it is set.
just use _pids(giving the user power), if not, set the style for the current
context with your default options, then use _pids.

though the program seems to have `subcommands' and the completer doesn't take
that into account and update the curcontext parameter to include the subcommand
into the command spot for more granular use of zstyle.
