Kugel Fuhr b2aceaea24 Fix behavior of .INCLUDE within a macro or .REPEAT. In the original code
.INCLUDE was executed after expansion of the macro or .REPEAT - which was
wrong and caused all sorts of unexpected behavior. Related issues/PRs
are #231, #1473, #2159 and maybe others.

Note: After this change error messages for nested macro/.include statements
may be wrong. This is an unrelated bug that was always there and got exposed
by this fix. The bug needs to be addressed in a separate PR.
