Newbie looking for a toy example of ediff-buffers demonstrating #f and #h

Hi - Newbie looking for a toy example SESSION of ediff-buffers demonstrating #f and #h.

You can put a small 2-3 lines file A and file B with lets say @ in first file and semicolon or hash in its place . Perhaps, also an empty brace in the first {} and a brace with some other text like {a b c} in the second.

I want to see how #f and #h is supposed to work.

Regarding two questions:

You are aware that {, }, [ and ] are all special characters in regexps?
Did you quote them to let them match themselves?

My Reply:
Yes, I have tried both ways with and without escape and results do not make any sense or difference. Actually escaped did not even give any difference, forcing me to go against the convention and try brace without escape.

Just to be clear: You are talking about fine diff highlighting?
I think whitespace is ommitted when highlighting fine diffs to make the
result appear less distracting in the majority of cases.

My reply:
Yes, but the documentation does not state so. 

Either code has to be made consistent to documentation 
or documentation has to be made consistent with the code.
