Customisable column indicator for folds

[Jeansen]

The help doc says with respect to folds:

An open fold is indicated with a column that has a '-' at the top and '|'
characters below it.  This column stops where the open fold stops.  When folds
nest, the nested fold is one character right of the fold it's contained in.

A closed fold is indicated with a '+'.

I'd like to be able to change these characters via my .vimrc. But so far, I cannot see how and think it is not yet possible. I know, it is a cosmetic (low priority) request. But if it is not too much work, I'd be happe to see it in some future release.

why do you want to customize it? The advantage of being hard coded is, that everybody right now already knows the meaning, while changing it, it might be confusing.

[Jeansen]

Well, generally speaking it is a matter of taste. And there are some good block/border symbols to use from Unicode. So it would look similar when using the tree command. On the other hand, IF someone changes it, then he/she knows what he/she has changed. I do not suggest to change the default. Just to make it configurable. Otherwise your argument would be true for almost every default in VIM mapped to something custom ;-)

Kudos to @brammool and everyone involved for implementing this and making a happy "vimer" even more happy ;-)
