If someone would like to work on this problem, I'd suggest introducing
an xerrorbar function instead of trying to make errorbar do it.

The special format strings for the errorbar function are likely to be
eliminated in the future as they are not Matlab compatible.

Longer term, the errorbar function will need to be fixed to generated
an errorbarseries object, but that can't happen until we have the
necessary infrastructure to implement the errobarseries object.
