[PATCH] scripts: commit-msg: recognize Git cut_lines

[Arsen Arsenović]

This prevents spurious failures from happening when someone sets
commit.verbose or passes -v to commit.
---
Hi,

When working on my previous patch, I was running into commit-msg mistakenly
triggering on lines that are part of the diff that can be optionally added
to COMMIT_EDITMSG via commit.verbose (which I have set globally, to review
patches as I commit them).

This patch prevents that from happening.

For the source of the cut_line, see wt-status.c:23 (cut_line) in the Git
sources.

Have a good day.
