if true, tail-fs-readable will consider the file as completely changed if its mtime is different, but the size is identical.

if false, tail-fs-readable will not be able to detect a modified file with a different content, but the same size.

It s about this particular case :

echo "some" > tailed.txt
echo "else" > tailed.txt

As a binary

npm i @mh-cbon/tail-fs-readable -g
tailf some.txt
  ctrl+c to quit
