We can either offer a migration plan, or continue supporting the old
format.

Needless to say, supporting the old format would make the code ugly.

As for the migration, there are three possibilities:
 1) migrate transparently on first call;
 2) error-out on old format, instructing to run with the --migrate
    option;
 3) error-out on old format, instruct to run another program to do the
    migration.

But the migration might not be that easy: some people (like me) may have
commented sections in their current .pwclientrc, so it is easier to
switch projects.

So, that's why I just decided to error-out on the old format, rather
than either migrate or support the legacy format.

Of course, the new .pwclientrc downloaded from the project's page should
be changed to include instructions on how to migrate, if needed.

The path of least surprise to the user is to support the old format, but
risks making the code a bit more complex...

What do you prefer?

Yann E. MORIN.
