+On Windows, square brackets do not have a special meaning in glob strings.
+However, python's glob module is written for unix-style globs in which brackets
+represent character classes / ranges.
+
+Calling glob.escape would also escape asterisk which may not be desired.
+So this module just provides a modified version of glob.glob which will escape
+only square brackets when called on windows, and behave normally on linux.
