Yes, I know.  But it is impossible to drag this effect into the Posix
world.  Resetting the write bit was a compromise.

Unfortunately, I don't know how to do that without breaking lots of
programs.  The original version of readdir was coded by DJ to skip
hidden files, but that proved to be a pest: literally every ported
program needed to work around that by setting the DJGPP-specific flag
that forced hidden files to be returned as well.  For example, if
readdir doesn't return hidden files, you cannot remove directories
with such files with "rm -r".

So we changed that in v2.02 to not skip hidden files by default.

This will not do what you want: as long as the user has write access
to the file, many programs won't do anything special with it.  For
example, `rm' won't ask you whether to remove it.
