When trying to detect the content type of the

uncompressed content it is often not enough
to read the same number of bytes, we already
read compressed. Since uncompress() allocates a
new buffer, we can increase the number of bytes
to read to the same size, we use in the case,
where the content isn't compressed.

Furthermore zero-terminate the read data to keep
assumptions consistent with the uncompressed case.
