It is probably smarter to avoid that corner case entirely.
Good idea.

I added a test which checks that a valid patch is produced and that
the signature from the file appears in the output.

In addition to addressing the suggestions from Jonathan I also
updated the Documentation.

This solution uses a static buffer to store the signature which does
create a size limitation (1024 bytes).  I considered a solution
using malloc but I could not figure out a clean way of determining when
to free the memory.

Thanks for the help and suggestions.
