There is a difference in function names.

I think that if you do plan on using a repository specific object as a
parameter in the function call, that you also rename the function to be
"repos" specific, such as

svn_repos_log_error(reposobject, level, "message")

so that the generic svn_log_error function can still exist. Perhaps this was
implicit to some but it should be stated.

On the same note, I strongly support a standard svn_log_* set of functions
that define our core logging APIs. Other module specific functions such as
those in svn_repos, etc. can then simply wrap the main svn_log_* APIs as was
suggested. Several people have alluded to this and Ben has directly stated
it here:

I don't think these are contradictory goals. For example, we could
