+/*
+  MSDN says, basically, that the maximum length of a path is 260 characters,
+  which is represented by the constant MAX_PATH.  Except when it isn't.
+
+  The maximum length of a directory path is MAX_PATH - 12 because it must be
+  possible to create a file in 8.3 format under any valid directory.
+
+  Unicode versions of filesystem API functions accept paths up to 32767
+  characters if the first four (wide) characters are L"\\?\" and each component
+  of the path, separated by L"\", does not exceed the value of
+  lpMaximumComponentLength returned by GetVolumeInformation(), which is
+  probably 255.  But might not be.
+
+  Relative paths are always limited to MAX_PATH because the L"\\?\" prefix
+  is not valid for a relative path.
+
+  Note that we don't care about the last two paragraphs because we're only
+  concerned with allocating buffers big enough to store valid paths.  If the
+  user tries to store invalid paths they will fit in the buffers but the
+  application will fail.  The reason for the failure will end up in the
+  event log and the user will realise the mistake.
+
+  So that's that cleared up, then.
