The subject of your email plus the part above the "---" line will be taken directly to be used as the commit message. So it should not include information that is inappropriate for a commit message.
You can put such information directly below the "---" line.
Please also see my comments below.

The line above seems to have been broken by your email program. It is important for efficiency reasons that patches be readable directly out of emails (e.g., by using "git am"). Please practice by sending the patch to yourself different ways until "git am" works on it correctly.

But actually, IMO this particular comment doesn't really belong permanently in the code. It rather belongs in the commit message, or in the discussion (under the "---"), or maybe it should be taken as an indication of a deeper problem (see below).

The code itself looks correct.
But, considering your comment, would it be appropriate for one of the functions to call the other?
