Underlying issue was temporary table of remaining lexemes for a token not being
updated (emptied) if only underspecified lexemes of the token met an agreement.
Effectively the token was left in its original state i.e. with all
original lexemes present, both those that were underspecified and the remaining
ones that did not met a weak agreement that was otherwise met via the
underspecified lexemes.

Note: one of the tests fails on purpose so everyone can see what it looks like.

refactor wcclrun a bit, add formatting options: --tabs makes it output plain tab separated data, -l and -g control local / global token counts

So such lexemes are always left in the end.
