delta: ignore base whose chains already don't match expectations
If we know the existing chain does not match our criteria, there is no point
to build a delta to append. This is especially useful when dealing with a full
text much smaller than its parent. In that case, the parent chain is probably
already too large.

Our full contribution guidelines are in our wiki, please see: https://www.mercurial-scm.org/wiki/ContributingChanges If you just want a checklist to follow, you can go straight to https://www.mercurial-scm.org/wiki/ContributingChanges#Submission_checklist If you can't run the entire testsuite for some reason (it can be difficult on Windows), please at least run `contrib/check-code.py` on any files you've modified and run `python contrib/check-commit` on any commits you've made (for example, `python contrib/check-commit 273ce12ad8f1` will report some style violations on a very old commit).
