Windows

If a too long pathname is detected on Windows, an informative warning is given. The maximum number of symbols in a Windows pathname is 256, including file separators '/' or '', but excluding the drive letter, and initial file separator (e.g. 'C:/'), and the string terminator ('\0'), cf. 'MSDN - Naming a File or Directory', Microsoft. In R, the limit is one symbol less, i.e. 255.
