Kalibera, that our code to look into system.call() stack was buggy and failed in staged installation, we revised code to .modifyqgaps completely; we now compute p(obj)(gaps) and check if any argument p of q(obj) falls within the gap range and then shift it to either the left or right endpoint of the gap acc. to args lower.tail and leftright. To avoid redoing this whenever slot gaps is changed, we store the unmodified q(obj) function in an internal variable ..q0fun which can also be used (if existant in the env() of q(obj)) to revert the gaps modification, and any gaps modification, instead of starting from q(obj) starts with ..q0fun (if this exists); otherwise, i.e., if ..q0fun does not exist, it uses q(obj) and afterwords stores the old q(obj) as ..q0fun ...

In addition the search interval is now more flexible: it is bound away from 0 below and from the upper bound from above, and this bound moves to the respective lower/upper bounds in up to 20 trials. Also, the search interval for .q2kolmogorov if argument 'exact' is TRUE (i.e., if pKolmogorov2x is called) has been refined.
