That depends upon context...

There is a semantic difference between checking that "file" is not a
_file_ versus checking that the a path itself (which may be a
directory or a "special file") does not exist. In this particular
test, the difference doesn't matter, so the conversion is sensible
enough, but it would save reviewers time if you, as author of the
patch, state that you carefully considered the distinction before
making each change.
