My summary of the situation, for the record: contrib\hooks\enforcer seems to struggle with empty files when using svnlook v1.6.9. I can't find if/how/where or rather, by whom, the contribs are maintained. v1.6.5 includes this change: "make 'svnlook diff' show empty added or deleted files (r38458)" - so that might be where the change happened. But r38458 description includes the following: "If we don't print any output for empty added or deleted files, hook scripts relying on 'svnlook diff' to gather information about files affected by a revision can get confused. E.g. contrib/hook-scripts/enforcer is known to be affected, it cannot enforce rules on added empty files." I can't find any record of "E.g. contrib/hook-scripts/enforcer is known to be affected". Hopefully one day someone who knows more about it will be able to confirm this as a problem in either svnlook or the enforcer script and possibly and fix one of them. If I could be sure that it was enforcer rather than svnlook that was wrong I could have a go at fixing it myself.
