+ *
+ * If the {@link windowsPathsNoEscape} option is used, then square-brace
+ * escapes are removed, but not backslash escapes.  For example, it will turn
+ * the string `'[*]'` into `*`, but it will not turn `'\\*'` into `'*'`,
+ * becuase `\` is a path separator in `windowsPathsNoEscape` mode.
+ *
+ * When `windowsPathsNoEscape` is not set, then both brace escapes and
+ * backslash escapes are removed.
+ *
+ * Slashes (and backslashes in `windowsPathsNoEscape` mode) cannot be escaped
+ * or unescaped.
