Is your feature request about something that is currently impossible or hard to do? Please describe the problem.

The docs for :h :find do not mention anything about the new 'findfunc'. Feels like this should be mentioned so people are aware of how :find interacts with findfunc. The current doc is one sentence:

:fin[d][!] [++opt] [+cmd] {file}
			Find {file} in 'path' and then |:edit| it.

Describe the solution you'd like

Mention that :find will use findfunc if set. Can figure out what it should specifically say if people agree with me on this.
