Commit range is including incorrect number of commits

[spiffcs]

What happened:
Chronical is identifying the correct commit range to search:

[0000] TRACE searching commit range since=04a55885ee162ec00548ec39df68c5b62cf213b5 until=1d013affc27ff04c45411183443def13ca136088

However it's computing 862 commits to examine rather than the 3 seen above

DEBUG release comprised of 862 commits

What you expected to happen:
I expected 3 commits to appear in the release

How to reproduce it (as minimally and precisely as possible):
There is an open grype branch called pipeline-parity if you pull from head and run make changelog this can be reproduced

Anything else we need to know?:

Environment:
osx
