I suggest that you forget hist (="old style" graphics) for this type of job and
use trellis graphics in package lattice, function histogram instead. True,
lattice has a bit of a learning curve, but I promise you it pays. No manual
subset selection, and "same scaling" is the default; you will even have some
problems when you want to force different scaling.

See http://dsarkar.fhcrc.org/lattice/book/figures.html

You could also have a look a ggplot2, which takes and elegant approach, but
still has a few rough edges.
