[patch] open folds on horizontal movements

[Christian Brabandt]

Bram,
I find it irritating, that folds open on horizontal movements depending
on where the cursor is.

For example open fold.c, move the cursor to a closed fold, Move the
cursor to the end of the line ('$'), now the fold opens. Close the fold
and press 'l'. The closed fold does not open, because the cursor did not
move.

This happens sometimes to me and I find this confusing, that
sometimes the fold does not open and sometimes it does.

So here is a small patch, that fixes it.

I'm not sure we need this change. It's actually not because the cursor
didn't move. If you use a command that fails, such as using "l" when
already at the end of the line, nothing happens. If you want to open a
fold intentionally, use "0", that never fails. Is there a good reason
to change this behavior?

Hi Bram!

The point is, when the folds are closed, the user doesn't know, whether
the cursor is at the end of the line so it's kind of unexpected that l
doesn't open the fold.

Christian
