/usr/share/vi/catalog/english (file after first compile)

Scenario:
- FreeBSD releng/13.0 i386
- Originally built in /usr/src using "make buildworld buildkernel <some parameters>" on FreeBSD 12.1 i386 [sic]
- Installed (installkernel installworld mergemaster) such that the system now runs FreeBSD 13.0
- After applying some (unrelated and minor) local changes to the tree, running "make -DNO_CLEAN buildworld buildkernel <some parameters>
- Installing into /usr/tmp/x using "installkernel installworld DESTDIR=/usr/tmp/x ..."
- Comparing contents of / to /usr/tmp/x

Result:
- Files where local changes were made differ (expected)
- Not expected: /usr/share/vi/catalog/english and /usr/tmp/x/usr/share/vi/catalog/english differ
- /usr/share/vi/catalog/english has 1472 bytes (on 12.2 it is much larger), whereas /usr/tmp/x/usr/share/vi/catalog/english has only 32.

Expected result:
- /usr/share/vi/catalog/english and /usr/tmp/x/usr/share/vi/catalog/english should be the same

Note: I just tried to reproduce this on amd64 and could not. But I had the same thing on another compile before (i.e., already seen at least twice).
