vcs-svn: add a comment before each commit
Current svn-fe produces output like this: blob mark :7382321 data 5 hello blob mark :7382322 data 5 Hello commit mark :3 [...] M 100644 :7382321 hello.c M 100644 :7382322 hello2.c This means svn-fe has to keep track of the paths modified in each commit and the corresponding marks, instead of dealing with each file as it arrives in input and then forgetting about it. A better strategy would be to use inline blobs: commit mark :3 [...] M 100644 inline hello.c data 5 hello [...] As a first step towards that, teach svn-fe to notice when the collection of blobs for each commit starts and write a comment ("# commit 3.") there.
