Someone with better Windows knowledge than me should explain how this works. Windows'
snprintf() just cuts out the last character in this statement:
snprintf(buf, 8, "--%s", "onto"); // result: '--ont', expected: '--onto'
All rebase tests now pass for me on Windows (Vista something, I have
yet to find where it hides its "uname" command)
