Allow multi-character DirArrows (#985)

Browse Source 
* Add debugging messages to diagnose issue #931.

* Echo the CWD and NERDTree root too.

* Ensure DirArrows are trimmed to a single character.

Actually, it's up to the user to make sure it's a single character after
leading and trailing spaces are removed. Spaces need to be removed so
that an accurate level of indentation can be calculated.

* Remove debugging statements

* Simplify the algorithm for calculating indentation level.

1. Replace the DirArrows with a single space.
2. Count the leading spaces.
3. Divide by 2.

This allows users to specify multi-character arrows, where a spaces
prevent characters printing on top of each other.
