fix(check_message): strip commit.verbose diff before validating

[jeromepin]

With commit.verbose=true, git appends the staged diff below a scissors line in the edited commit message file (example). The diff isn't comment-prefixed, so sed '/^#/d' leaves the diff in place, right after the commit header with no blank line, failing the structure check.

I tested too by disabling commit.verbose and it still works.

Why ? Because I like being reminded of what I did when typing my commit message 👍
