Revision 1688c9a4894df517241026c7a3848bdc84607986 authored by Jeff King on 23 August 2018, 00:49:56 UTC, committed by Junio C Hamano on 23 August 2018, 17:08:51 UTC
Even with the newly-tightened "---" parser, it's still possible for a commit message to trigger a false positive if it contains something like "--- foo". If the caller knows that it has only a single commit message, it can now tell us with the "--no-divider" option, eliminating any false positives. If we were designing this from scratch, I'd probably make this the default. But we've advertised the "---" behavior in the documentation since interpret-trailers has existed. Since it's meant to be scripted, breaking that would be a bad idea. Note that the logic is in the underlying trailer.c code, which is used elsewhere. The default there will keep the current behavior, but many callers will benefit from setting this new option. That's left for future patches.
