Enhancement request for tee - please make tee reopen/recreate files on write

[Hubmann,Alexander]

Hello tee developers,

I have come across a situation where it would be very beneficial if tee could 
reopen/recreate a file each time it starts writing to it.
So, e.g. logrotate could move away the log file and the file would get 
recreated on the next output to write to.
My issue described here: 
https://stackoverflow.com/questions/63286536/avoid-sparse-files-with-tee-and-logrotate

Currently tee continues to write to the deleted inode. And it creates sparse 
files if the file it writes to gets "truncate -s 0" - although tee -a seems to 
prevent this.

Thanks,
Alex.
