`port info --line` produces multi-line output

[raimue (Rainer Müller)]

The multi-valued maintainers released with 2.3.5 broke the output of port info --line, which can now produce multiple lines per port.

$ port info --line --maintainers nginx
Email: cal@macports.org
Email: mps@macports.org
Policy: openmaintainer

This should produce only a single line.

As a follow-up, this output does not look good either. It should be one line per field.

$ port info --name --version --maintainer nginx
version: 1.11.6
maintainer: Email: cal@macports.org
Email: mps@macports.org
Policy: openmaintainer
name: nginx

I noticed this while implementing this, but the output is equally broken for other fields that contain linebreaks, e.g.:

$ port info --name --version --long_description moreutils
version: 0.59
long_description: moreutils includes the following utilities:
- chronic: runs a command quietly unless it fails
[…]
- zrun: automatically uncompress arguments to command
name: moreutils

$ port info --line --long_description moreutils
moreutils includes the following utilities:
- chronic: runs a command quietly unless it fails
[…]
- zrun: automatically uncompress arguments to command

How should we deal with those?

port info: Re-implement broken subfield separators

The subfield_sep variable was not used anymore after 30c27d5, replace it
with specific separators for the different output modes.
