more email cleanups?

[René Ladan]

Hi,

now that projects/entities is merged, I grepped through head/share and
head/en_US.ISO8859-1 for literal @freebsd.org addresses.  The results
are at [1] and [2] (after filtering out the standalone
<email>committer at FreeBSD.org</email> for the status report sources and
non-XML files).

Should these usages (or some of them) be converted too?  On one hand the
sources would be cleaner, but on the other hand there are quite some
append-only or write-once or files, such as share/xml/news.xml or
en_US.ISO8859-1/htdocs/releases/*
