commit: pass --no-divider to interpret-trailers
When git-commit sees any "--trailer" options, it passes the COMMIT_EDITMSG file through git-interpret-trailers. But it does so without passing --no-divider, which means that interpret-trailers will look for a "---" divider to signal the end of the commit message. That behavior doesn't make any sense in this context; we know we have a complete and solitary commit message, not something we have to further parse. And as a result, we'll do the wrong thing if the commit message contains a "---" marker (which otherwise is not syntactically significant), inserting any new trailers at the wrong spot. We can fix this by passing --no-divider. This is the exact situation for which it was added in 1688c9a489 (interpret-trailers: allow suppressing "---" divider, 2018-08-22). As noted in the message for that commit, it just adds the mechanism, and further patches were needed to trigger it from various callers. We did that back then in a few spots, like ffce7f590f (sequencer: ignore "---" divider when parsing trailers, 2018-08-22), but obviously missed this one.
