This method used the brittle "Path._escChars()" method to do its
work. This created problems when 'shellslash' was in use on Windows
because excessive escape characters (i.e., backslashes!) are
interpreted by Vim as additional path separators.
The above problem made it impossible to edit files with weird names
using the NERDTree on Windows with 'shellslash' set. For example,
'+' should be escaped with ":edit", but '(' should not. So, when
escaping '(', Vim on Windows correctly sees the start of a new
directory in the path.
This was reported in five issues which may be read for further
details and commentary.
Fixes#398, fixes#474, fixes#653, fixes#674, and fixes#733.
