bug#58820: [PATCH] Calculate age cutoff at n-th midnight instead of n*24h mark |

* lisp/gnus/gnus-sum.el (gnus-summary-limit-to-age): Calculate cutoff to
point to n-th past midnight (1st is 00:00 today). This way messages sent
between n*24h mark and the next midnight will be excluded (or included
if limitting to younger messages), which seems more intuitive when users
are asked to enter age in days.
