Tail bug

[Petr Dolezal]

There is a stupid bug in tail, I think. When tail is used with -f option
and source file is overwritten, then error message "==> filename: file
truncated <==" is written to standard output instead of standard error
output. This is very unpleasant because you can't get rid of these error
messages easily, simply, although you try "tail -f some_file 2>/dev/null",
you get error messages to standard output anyway - I think that is not
right.
