Invalid add_users command in Portfile

[pcafstockf (Frank Stock)]

Dovecot port attempts to add two user accounts (_dovecot and _dovenull). Portfiles support adding multiple accounts, but it needs to be done using a single add_users command.

As currently written, only the _dovenull account ends up actually being created.

Instead of:

add_users ${default_internal_user} group=${default_internal_user} realname=Dovecot
add_users ${default_login_user}    group=${default_login_user}    realname=Dovenull

The Profile needs to be:

add_users ${default_internal_user} group=${default_internal_user} realname=Dovecot ${default_login_user}    group=${default_login_user}    realname=Dovenull

Or for readability maybe:

add_users \
    ${default_internal_user} group=${default_internal_user} realname=Dovecot \
    ${default_login_user}    group=${default_login_user}    realname=Dovenull

Note the line continuation chars.

Forgot to add a link to the add_users documentation (​https://guide.macports.org/#reference.keywords)
