Hi,

it looks like the c++ version adds a newline to the end of the output (at least withj the --multi dir option) but the golang version does not. According to POSIX, a file should end with a newline so I'd suggest changing the go version to also include the newline:

Here is a diff for a file generated by c++, then re-generated by the go version:
