No, I didn't miss it. However, by using the Apache logging code
(and in the future a potential APR version of it) you also get
logging via syslog/Windows event log which means you may not need
direct write access to the log files.

In any case, if someone *is* using file:// to access their repos
then I don't know how you can ever provide "accurate" logging since
the repos can be accessed outside of Subversion. The best you can
do is say "for accurate logging you must use either mod_svn or
svnserve without SSH" and explain why file:// and svn+ssh:// may not
be reliable. People that care about accurate logging will use the
right schemes to get there - just provide the ability to log things
(not enabled by default) and let the users decide how best to
configure it on their systems.
