Just a general question about the usage of "int" here (and at other places):
Is there a special reason for new code to allow num_bits to be negative ?
To my knowledge all the size_t definitions these days are positive,
because a size can not be negative.
As a reader of the code I always wonder if there is a special meaning with
negative values, (as the result of read() to indicate an error) but there isn't.
Should we use
"unsigned" here ?
or "unsigned int" ?
or "size_t" (Which may use 64 bits, which feels like a overkill)
