Exclusive ranges get wrong trailing delimiter for word targets

[pokey]

In the following:

aaa_bbb_ccc_ddd_eee

If you say "chuck second until fourth word", you get

aaa_eee

Instead of

aaa_ddd_eee

The problem is that we take the trailing delimiter from the active target in the range even if we're excluding it:

cursorless/packages/cursorless-engine/src/processTargets/targets/SubTokenWordTarget.ts

Line 66 in 3fe5d81

trailingDelimiterRange: endTarget.trailingDelimiterRange_,

We should really downgrade the target to an untyped target if either end is excluded,
because it no longer can be viewed as a range of the given type. For example "token air until bat" in aaa bbb, is not really a token range, because it is aaa .

I think we probably should stop leaving so much of createContinuousRangeTarget to be determined by the derived class. We should try to solve the circular dep while we're there.
