I am afraid that this is leading us in the wrong direction.
What would be the first reaction if somebody sees such a
message?
The message implies that the user said "foo/" which would be
ignored and the right substitution is "foo". If that is the
right substitution, why doesn't the stupid "git" program do
that for the user automatically?!?!?!?!
See?
"Remove the trailing" suggestion assumes that we would want "foo/"
and "foo" to mean the same thing.
Maybe we do, but we usually match both directory "foo/" and
regular file "foo" when you say "foo", and we match only
directory "foo/" when you say "foo/", as you saw in the ls-files
example.
While I am not 100% convinced that we want to keep the
distinction between these two forms, I am far from thinking that
the existing distinction in other parts of the system is useless
and should be removed.
Maybe we would want to drop this distinction in the gitignore
entries, and the apparent inconsistency may not hurt in reality.
If that is what we would want, that is fine, but then we
shouldn't give a warning with a stupid piece of advice, but
instead just do it ourselves.
Like this on top of 'master' (i.e. discarding all the previous
patches), perhaps...

[PATCH] gitignore(5): Allow "foo/" in ignore list to match directory "foo"
A pattern "foo/" in the exclude list did not match directory
"foo", but a pattern "foo" did. This just strips the trailing
slash from such input.
This makes the behaviour slightly inconsistent with that of
pathspecs, where "foo/" only matches directory "foo" and not
regular file "foo" and make "foo/" in the ignore list match
regular file "foo" happily. This may hopefully does not matter
in practice.
