perldelta for bfa371b621
(cherry picked from commit 43441260a4eb87e18dc79b9ce0e82a45c229dd75)

[What you see above this is what ‘git cherry-pick’ generated.  What
 comes below is the committer’s own commentary.]

25b4c20b7 (update perldelta) accidentally removed the text added by
b380e583f8 (perldelta for 2c60386e935).

However, the text added by b380e583f8 was taken from 6f9296e1cb, which
added to blead the perldelta entry for 8c9d3376fbf, which has not been
cherry-picked to the maint-5.18 branch.

2c60386e935 was cherry-picked from bfa371b621 and documented in
perldelta by 43441260a4 (the source of this commit).
