text-property-any (and t-p-not-all) seems to do the same, except it only
searches forward. Is there some other difference I'm missing (other
than the `cycle' which doesn't seem tremendously useful)?
Differences compared to text-property-any:
- Includes helper functions 'search-property-forward' and 'search-property-backward' which move point and closely match the interface and behavior of 'search-forward' and 'search-backward'. (Except for 'count'.) The interactive use is nice: when you need it, you really need it.
- I don't remember what the original use case was for 'cycle'. Possibly to emulate the effect of hitting TAB in Emacs Muse to go to the next URL (behavior that I would remove if I was starting again from scratch).
- In the initial release of the file to gnu.emacs.sources, I wrote this blurb. Maybe there was a related shortcoming in text-property-any at the time.
