[PATCH] 5-make-release-commit: fix rstheader

[christian.ehrhardt at canonical.com]

From: Christian Ehrhardt <christian.ehrhardt at canonical.com>

The printf magic fails trying to interpret "-" as option and thereby breaking
the top level headers.
   printf: -%: invalid option
   printf: usage: printf [-v var] format [arguments]

Instead of relying printf expansion, fall back to the more trivial
printf n times which works with any char.
