Yes, qgit uses git-commit, but issue is different.

qgit uses the output of git status as a 'default text' used in the
commit dialog. When commit button is pressed, after some message
editing by the user,  the comment lines are stripped _before_ to save
the content of commit message in a temporary file to be used by
git-commit with -F option.

The comment stripping is done by this code:

	msg = textEditMsg->text();
	msg.remove(QRegExp("\\n\\s*#[^\\n]*")); // strip comments
	msg.replace(QRegExp("[ \\t\\r\\f\\v]+\\n"), "\n"); // strip line trailing cruft
	msg = msg.stripWhiteSpace();

as you see it rely on the  '#' character.

So conclusions are:

1) It's ok to let git-comit do not strip comment lines, it's already
done by qgit.

2) Please don't change git status output to use another symbol to mark
comment lines because it will break line stripping code.
