Simplified .dot codegen:

- draw a single arrow for all transitions between two given states
- label all arrows with corresponding character ranges in square
  brackests (no "default" label, single characters also appear in
  square brackets)

early parts of the generated code, e.g enum with condition names

pass.

I isolate all (I hope so) these things and generate stubs for them,
which are filled later. I restructured output as follows: the whole
output consists of source and header, each of them is a list of
blocks (corresponding to re2c blocks in source file), each block
is a list of code fragments (which can be either regular strings
with code or stubs that will be filled later).
