I think creating an intermediate commit state where it's both doing lexing for 
tokens //and// source minimization is not worth the trouble.
When committing I could merge the last 2 patches together into one commit (or 
all 4 of them into a commit), so there's no commit state where depscan 
performance is regressed.
I mostly separated them like this for reviewing convenience.
