cogito: commit message from stdin and -m switch

Hi, cg-commit(1) states

-m MESSAGE
       Specify the commit message, which is used instead of starting up
       an editor (if the input is not  stdin,  the  input  is  appended
       after  all the -m messages). Multiple -m parameters are appended
       to a single commit message, each as separate paragraph.

What happens is that the message on stdin overrides the message given through the -m switch:

 $ cg-init -m initial

This also breaks the selftests with stdin not connected to a terminal (so in Debian package autobuilder environment):

 $ make
 Generating cg-version...
 $ make test </dev/null 
 make -C t/ all
 make[1]: Entering directory
 `/usr/local/src/Debian/Upstream/GIT/cogito/t'
