[ENH] beginsEndsWith-bp ( Method comments... )

[goran.krampe at bluefish.se]

Ok, perhaps my advice was slightly dubious - the code turned out to be a
bit hard to read IMHO because the parameter name got so long. But
perhaps you can simply format it a bit different.

Most importantly - add some proper method comments!

I will not approve code into the Collection hierarchy that doesn't have
proper short-and-to-the-point method comments. :-)
