some clues truncated in PUZ export

[TheOriginalOrthonormal]

When a clue has more than one period in it, it is truncated immediately before the second period when exported to PUZ format.

For instance, a crossword is created with 1 across being "First U.S. President". It is exported to PUZ format. When loaded into any program that supports PUZ format, the clue becomes "First U.S" I have tested this with: Across Lite Mac and Windows versions Puzzle Solver (https://www.crosswordsolver.info/) HTML5 PUZ file reader (http://derekslager.com/puz/) loading back into Phil from the PUZ file
