commit -C: skip blank lines at the beginning of the message

Consistent with the pretty-printing machinery, we skip leading blank
lines (if any) of existing commit messages.

While Git itself only produces commit objects with a single empty line
between commit header and commit message, it is legal to have more than
one blank line (i.e. lines containing only white space, or no
characters) at the beginning of the commit message, and the
pretty-printing code already handles that.
