When reconstructing lines from a macro expansion, make sure that lines
at different levels in the expanded code get indented correctly as part
of the macro argument.
Add configuration to specify macros.
Macros will be expanded, and the code will be parsed and annotated
in the expanded state. In a second step, the formatting decisions
in the annotated expanded code will be reconstructed onto the
original unexpanded macro call.
Eventually, this will allow to remove special-case code for
various macro options we accumulated over the years in favor of
one principled mechanism.

The unused variable fix also remove the test output of the tokens
that do not match, making debugging tests harder. Undo the semantic
changes of the build fix.
MacroUnexpander applies the structural formatting of expanded lines into
UnwrappedLines to the corresponding unexpanded macro calls, resulting in
UnwrappedLines for the macro calls the user typed.
