using ssl for commits and template commit messages

I have two questions.

1. Does anybody know if it's possible to require ssl only for
performing commits? I tried this, but it redirected to https even when
I wasn't doing commits:
<Location /svn/pub>
    DAV svn
    SVNParentPath /srv/svn/pub

    # user authentication
    AuthType Basic
    AuthName "Public Subversion Repository"
    AuthUserFile /srv/svn/pub/svn_passwd
    AuthzSVNAccessFile /srv/svn/pub/svn_access

    # authentication for user commits
    <LimitExcept GET PROPFIND OPTIONS REPORT>
        Redirect /svn https://www.tomek.ca/svn
        Require valid-user
    </LimitExcept>
</Location>

2. Is it possible somehow make a template for messages commited
depended on the user doing the commit?

To be more clear, I like to have every message start with "Real Name
<emaill address>". Is it possible to generate or provide a template
for each user, so it gets filled with the users name and email address
(preventing me from having to type it in on every commit)
