[PATCH 8/8] git-remote-testpy: call print as a function

[John Keeping <john@keeping.me.uk>]

This is harmless in Python 2, which sees the parentheses as redundant
grouping, but is required for Python 3.  Since this is the only change
required to make this script just run under Python 3 without needing
2to3 it seems worthwhile.

The case of an empty print must be handled specially because in that
case Python 2 will interpret '()' as an empty tuple and print it as
'()'; inserting an empty string fixes this.
