Unless there is something I'm not thinking of, I don't see the legacy
fixed format files as being an issue. By using the appropriate
suffixes, we can drop the free-format flag and let the compiler figure
it out. Moving everything to .F90 still requires the same number of
name changes and file modifications.

That said, if people want everything free-format, we can include the
conversion as part of the script and do everything at once.
