Our proposal states that repos/conf/repos.conf has two variables that
allow administrators to decide where logfiles live. We can create a
special value for these variables that means "send to STDOUT". Would
that satisfy your feature request?

How is that different than my proposal, whereby the "svn_repos_t"
object contains all the information to output to the log? I see no
svn_log_error(logobject, level, "message")
svn_log_error(reposobject, level, "message")

It does? What values? Where? That's news to me.
My plan is currently in line with what ghudson has been suggesting:
no need for a calling process to cache the current 'global loglevel'
at all. The loglevel lives inside the repos object. We pass
varargs into svn_log_error(), which can then *internally* decide to
construct the message or not, based on repos->loglevel's value.

Each *library*? People are already criticizing my design for
creating too many logfiles, rather than one "uber logfile". I don't
see why it would be good for every single svn library to start
dropping logfiles. Can you explain?
