I'm beginning to get the sense that supporting delegates directly might not
be too hard.
It's related to the mental trick that created the Aha of using restarters:
namely, just pretend that a simple, straightforward solution exists, and
then look for it :-)
In this case, we can tell whether a delegate extends past the present line
by having it return len(s) + 1 when it has started matching a cross-line
pattern. In that case, we remain in the *delegated* stated. Otherwise, we
continue in the *delegator* (caller) state.
For example, the difference between:
#define WIPEOUT 0 /*
* comment line 1.
and
#define /* comment */ WIPEOUT 0
is that the delegate returns len(s) + 1 in the first case and n < len(s) in
the second.
It might work.
Another way of thinking of this is that no matter what is happening, we are
"really" only colorizing the current line. It should be simply a matter of
keeping track of what colorizing state we are in, and passing that state to
qt at the end of the line :-)
