Do you know whether long logical lines are a problem for MSVC,
or is it just long physical (i.e. preprocessor) lines?

C and C++ can be mechanically fit to a minum line width using backslash
continuations. Backslash continuations can be in the middle of a token,
so it can be done without regard for even token level syntax.
A trivial text filtering program can do it.

Here is chpped-up Hello, World:
