Title: Fix representation of negative zeroes

Without the --no-squeeze option, negative zeroes were represented by
zeroes which lead to incorrect behavior. For instance, 1/-0
(i.e. -Infinity) was transformed into 1/0 (i.e. Infinity).

This patch also improves the representation of negative infinity (1/-0
instead of -1/0; cf. #410) which does not require white space or
parentheses in expressions such as x-(-1/0).
