changing log entries in just one file will introduce inconsistencies.
afaik, one log entry usually represents the log entry of each 'changeset'
applied to a file. And (at least in cvs) is gets copied to all
modified files. if users modify the $log$ entry of a single file,
svn would/will have to re-scan the $log$ entries for
intended modifications and then replace the changeset logs,
then the next update must redestribute the modified $log$
to all other files that contain the same 'changeset'.
I wouldn't recommend editing the content of $log$ inside a
WC file at all.
If there is need to edit log messages, svn already provides nice features.
If there is need to "trim" old log messages, maybe
something like $Log(startrev=20,endrev=head)...$ could be
added when the $log$ feature is added to svn?
How would differently edited $log$ files react when
merging different revisions? (i can image baad things;-)
But probably you would even need more specific separations,
like some $internallog$ and a $publiclog$ ?
Editing inside of $log$ also has the sideeffect that someone
can maliciously/accidentally modify another persons log entries
which should probably require additional security/permission flags.

:-)
c.a.t.

P.S:

i didn't bother to look but CVS mailing lists
probably contain a lot of reasons why not to use/edit it :-)

p.P.S.:

I wonder what kind of secrets
you write in those logs? ;-)
