- Corrrect some offsets of patch hunks
- Remove change in get-mtime.c as mandb-symlink-target-timestamp
now catch the random format changes

- update to 2.10.2:
* Regenerating man-db's build system now explicitly requires Automake >=
1.14. (This was already the case since at least man-db 2.10.0, but was
previously undocumented.)
* Make `man -H` sleep for a few seconds after starting the browser, since
it may background itself before loading files (Dr. Werner Fink).
* If an override directory is configured using `--with-override-dir`, it is
now applied more consistently when building the manpath, and whether a
page was found in an override directory is considered when sorting
candidates for display (Mihail Konev).
* Make the man-db manual build reproducible.
* Add some hardening options to the `systemd` service.
* `configure` now has a `--with-snapdir` option, for use on systems where
`snapd` is configured to use a directory other than `/snap`.
* Fix occasional `mandb-symlink-target-timestamp` test failure.
* Fix inadvertent reliance on a GCC extension that caused build failures
with Clang.
* Fix building without `iconv`.
- drop man-db-2.7.1-firefox.dif (upstream)
