Lynx seems to rely on this behavior for "ARTICLE <message-id>"
Tested with Lynx Version 2.8.8dev.12 (22 Feb 2012) on Debian wheezy.

Still not changing or adding new caches or modifying our data layout,
but things seem to work well for the common case.
The most important change is the new long response API which will help
us even after any future optimizations we make. We should be able to
stream millions of messages without excessive buffering and memory
usage.
Eric Wong (12):
nntp: use write_buf_size instead write_buf
nntp: introduce long response API for streaming
nntp: use long response API for LISTGROUP
nntp: implement command argument checking
nntp: XOVER does not require range
nntp: speed up XHDR for the Message-ID case
nntp: implement XROVER, speed up XHDR for some cases
nntp: implement XPATH
nntp: fix logging of long responses
nntp: fix ARTICLE/HEAD/BODY/STAT
nntp: log to FDs given by the Nntpd module
nntp: article lookups by Message-ID may cross newsgroups
