Ensure initial PTY size matches Terminal (if any)
If a PTY has a terminal_path set to a valid Terminal, then ensure that the initial cols and rows of PTY match the cols and rows of the Terminal when calling fork() or open(), otherwise PTY will output wrong-sized data for the Terminal until resized. Fixes #56.
