Re: 'withfile' function implementation

[David Boyce]

Thanks, this will make a lot of people happy.

One nit: as mentioned earlier I think it would be good to document the
relationship of $(file ...) with timestamps. Assuming nothing special
is done (I haven't looked at the code) then writing a null string will
not update the timestamp. I tried to make a case in favor of doing
something special but either way it would be good to get the behavior
on the record.
