I have tried it. Unfortunately, it is slow and ... well, it doesn't show
Changelog to me :-) Say, this is full output:

emerge -l sun-jdk
>>> --changelog implies --pretend... adding --pretend to options.

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild R ] dev-java/sun-jdk-1.6.0.05-r1

You already have the latest version installed, so there are no changes to
show.

Neil,

I'm not interested in (probable) installation at all, rather in
Changelog' contents only.

Your original question was rather light on such details, and also omitted
to mention why more/less/most are inadequate for your needs.

I'll try being nicer if you'll try being smarter.

Neil,

My first message was:

Subject: fast CLI package-Changelog viewer
Body: Is there such one?

I agree, my English is ugly. I'll try to explain. Saying "viewer" I mean
something like this:

logviewer kdelibs

will "produce" the same output as, say,

less /usr/portage/kde-base/kdelibs/ChangeLog

You see, it is impossible to remember all packages' dirs. Of course, I
can use 'q' or 'eix' to find a dir and then type in a long 'less ...'
command. But, well, why do all these 'eix' and 'q' exist? I think to
save some users' time. Is my intention more clear now? :-)

Yes it is, but a very short shell script would handle this

#!/bin/sh
less $(portageq portdir)/$(eix --exact --only-names $1)/ChangeLog

Thanks, it works! (except for overlays)

Neil will surely provide an adequate answer, however, if your needs
aren't too sophisticated, you could put together something like

$ cat logviewer.sh
#!/bin/bash

if [ -z "$1" ]; then
echo "Must specify package name!" >&2
exit 1
fi

p=`eix --only-names -e "$1"`

if [ -z "$p" ]; then
echo "$1: No matches found" >&2
exit 1
else
howmany=`echo "$p" | wc -l`
if [ "$howmany" -gt 1 ]; then
echo "Many packages with the same name, refine search string:" >&2
echo "$p" >&2
exit 1
fi
fi

c="/usr/portage/${p}/ChangeLog"

if [ -z "$EDITOR" ]; then
EDITOR=`which vi`
fi

"$EDITOR" "$c"
---------

You can also remove the "-e" from the eix line if you want approximate
matching (that will require you to specify the category almost always
though).
Hope this helps.

It is more a starting point than a complete solution You could also
modify it to do a regexp search is the exact match fails.
