The value of (text-property-any start end 'foo "bar") is always nil,
because text-property-any in effect uses `eq' to check property values.
Would there be bad consequences if it used `equal' instead? If this is
not a viable option, is there a recommended way to find out if some
character has a property with a particular string value? I suppose
looping on next-single-property-change and testing for `equal'ity will
work; is that the best way? (My use case is a display property with a
string value.) Thanks,
Steve Berman

There are places where code expects properties to be compared with
`eq', yes. So we could add what you're requesting, but only as
an option. E.g. add a "compare-function" option that can default to
`eq' but can be set to anything else you fancy.

Sounds like a good idea.

Hi
would it possible to change text-property-any this way :
text-property-any start end prop value &optional object
becomes
text-property-any start end prop &optional value object
If the "value" param is not passed, Emacs only checked if prop is not nil ?
It would be useful for web-mode.el
Cheers

This is called text-property-not-all.
