Matching maintainers

[Adam Mercer]

Hi

For checking if there are any updates to the ports I maintain I use
the following:

port echo maintainer:ram | xargs -n 1 port livecheck

however this returns ports that I don't maintain but the maintainer
field starts with ram, e.g. atf and perforce. How can I match ram as a
complete string? I've tried ending the match string with $ to signify
the end, but then this doesn't match any ports where there are two
maintainers, e.g. openmaintainer.

Cheers

Adam
