# CHANGED 12-10-27. OK, here's the deal. We must open in binary mode
# on Windows because silly MiKTeX inserts ASCII control characters in
# over/underfull warnings. In particular it inserts EOFs, which
# stop reading altogether; reading in binary prevents that. However,
# that's not the whole story: if a FS character is encountered,
# AND if we invoke splitlines on a STRING, it sadly breaks the line
# in two. This messes up line numbers in error reports. If, on the
# other hand, we invoke splitlines on a byte array (? whatever read()
# returns), this does not happen---we only break at \n, etc.
# However, we must still decode the resulting lines using the relevant
# encoding.
# Note to self: need to think whether we don't want to codecs.open
# this, too... Also, we may want to move part of this logic to the
# builder...
