    The MOVF won't change the contents of register "f", but some
    registers -- I/O ports, timers, etc. -- can change on their own,
    so if you're reading THOSE registers, you can't always depend on
    two consecutive MOVFs reading the same value.

    If register "f" is a General-Purpose File Register, though, it
    won't change unless your software changes it... So two
    consecutive MOVFs will each read the same value.
