I think I agree Andres, there are already comments in the appendShellString
function to this effect - they say that CR/LF chars in a file name are
mostly used for malicious hacking attempts anyways - I know I've hardly
ever needed a newline in a file name.
Did you see anything else in my code that you have recommendations about?
I made sure to free the PQExpBufferStr vars that I allocated.
Best,
Ryan
