Note that these are not the "tee" semantics that we all know and love.
The command line is
tee [ -i ] [ -a ] [ file ] ...
where -i is "ignore interrupts", which we don't care about, "-a" is to
append rather than overwrite existing files, and "file" and following
are the names of zero or more files into which a copy of stdin is
written, along with being sent to stdout.
So, technically, you'd want to open a vector of zero or more files, and
write each line into each of them as well as onto stdout. This is a
few more lines of code, but still not exactly a nightmare.
