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

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.

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.
