¿on purpose? pdfinfo -v etc. are perfectly valid calls and should of course
return the error code 0, the error code 99 is signalling "other error"
according to the man page. I know of no other program returning an error code
for successful actions like --help etc.

A quick look at the code shows the reason for the bug: all cases showing the
version and/or help information are lumped together. Some of them (invalid
options) should return 99, others (asking for the version or help info) should
not.
