I think the usual rule is to stick to the prevailing conventions in the
file when it's got a consistent style that's different from ours.  When
adding entirely new code, even if intimately related to some existing code
with different style like malloc, whenever it makes sense to do it in a
separate file then that is the best thing to do and the new files of course
use our normal style.  When the right thing to do is modify an existing
file that has a different style we're intentionally preserving, go with
the local flow.


Thanks,
Roland
