[PATCH]Upgrading pre svn1.2 repositories to svn 1.6 fails(upgrading to 1.5 succeeds though!)

Hi All,

Upgrading pre svn1.2 repositories to svn 1.6 fails(upgrading to 1.5
succeeds!).

Attached patch fixes it.

If there are no objections I will commit it tomorrow.

With regards

Upgrading repositories created with pre svn1.2 fails.

* subversion/libsvn_fs_base/fs.c
  (base_upgrade): Pre 1.2 svn repositories do not have $REPO/db/format file
   so do not fail on such a case.
