Issue #537: Fix dir arrows not functioning properly

[adityanatraj]

added characters that are special when within character
classes in a regular expression to the escape(...) call
when building s:dirArrows.

this does not fix when ' ' or '' are your dirArrows and you
can't open up subdirs. i think that's an issue with how nerdtree
distinguishes things to traverse in the filetree.

this fixes: #537

Please bring back the option

let g:NERDTreeDirArrows=0

This used to work fine, now it's gone, not sure why it was removed.

what did

let g:NERDTreeDirArrows=0

do ?

I'm sorry, I don't know what that did, I'm relatively new to NERDTree

It disabled the ascii arrows in favor of + and - for directories.

@mdu4rt3 I cannot add that option as feature changes/behaviors are outside the scope of this PR. This is simply to fix the current issue with the broken characters for dir arrows.

If you notice within the CHANGELOG here, the behavior you requested was purposefully removed.
