The problem I see with that is the "MIDDLE|LEFT" should be read as a
single enum, while "MIDDLE LEFT" should be read as 2.  Using the usual
fill character for the separator would make it impossible to have more
than one BITFIELD-style enum on one line and prevent operator>> from
being able to properly read a BITFIELD-style enum without straying
from the usual operation of operator>>.  And using the "one line with
all the values of the enum" is just using ' ' and '\n' as the
separators instead of '|' and ' '.  Also, '|' matches the in-code
usage of enums -- "MIDDLE|LEFT", once read, has the value MIDDLE|LEFT.
