tail: follow multiple files
tail: follow multiple files

If multiple files are passed as arguments with the -f option, a vector
of BufReaders is built as the files are first tailed, so that follow()
can take control for the rest of the time the program is running.

follow() loops over each reader and prints all new available content on
each file before moving on to the next.
