I think it should be checked in.  I don't have intimate familiarity
with this code, but I did look at the problem and make the patch.

The other code in the file stores numerical values into the
`bindat-raw' using aset, and then wants to return the whole thing as a
unicode string containing those byte values.  The old code made a
vector, stored into it, and turned the vector into a string using
`concat' -- however that ends up making a _multibyte_ string (I don't
know whether this is a bug in concat or not).  The new method of
making a string initially and storing directly into it results in a
unibyte string, which is what is desired (this method is also more
efficient).
