Fix hang when using errorbar with empty dataset (bug #45554).
* __errcomm__.m: Use concatenation to append new errorbar plots to retval,
rather than assignment which can fail if the RHS is empty.
* __errplot__.m: Determine number of plots by checking number of columns in
dataset, but only if dataset is not empty (row is zero for example). Only
process a legend key if the number of plots is greater than 0.
