Severity: normal

The magic format does not seem to include any way to handle
length-prefixed strings with a non-byte length.  I want to handle a
file format which prefixes strings with their 32-bit length, but I see
no way to do this with the current magic format as specified in magic(5).

Ideally, I'd like some way to tell a pstring where to get its length
from, using a syntax like that of computed offsets.  For instance:

....
>>>>&4 pstring(&0.L) \b, name "%s"

Alternatively, introducing new types like pstring which use 16-bit and
32-bit lengths would work, but that would require specifying all the
details of length endianness in the name of the type, and the magic
format already includes a perfectly good syntax for that.
