=============
- Fix incorrect interpretation of "pre-options". Previously, all
non-expression options were considered "pre" and were floated in front of any
supplied paths. This was incorrect; only a few of the "pre-options" belong
before the paths, and the rest belong after the paths.
- Add support for new ``find`` switches.
- Treat ``-exec`` as an action to avoid spurious extra ``-print`` when using
excluded files (e.g., ``findx -stdx -exec echo +`` used to have the default
action ``-print`` appended because ``-exec`` wasn't correctly recognized as
an action).
