Is there someone out there who can explain this... is it plain legacy?
If there is no better explanation, lets just have it added to the archives.

 I bumped into this while moving files between OS'es... using tar.
In fact tar has more restrictions on filenames, making me wonder whether all
really are necessary. (WinRAR extracted more files than tar)


FAT, FAT32 and NTFS (W2K tested) doesn't matter - not even using
explorer[1], so it is the OS filesystem(s?) doing this, not cygwin.
