"pos" now returns 1 if the argument is greater than 0, otherwise it returns 0. This is consistent with the common mathematical definition of the "pos" function: https://en.wikipedia.org/wiki/Sign_(mathematics) However the previous implementation in which 1 was also returned for a 0 argument is useful in many situations so the "pos0" has been added which returns 1 if the argument is greater or equal to 0. Additionally the "neg0" has been added which returns 1 if if the argument is less than or equal to 0.

The config.*/example directories contains various example configuration files for the corresponding shell:
