OK.


From: Mikulas Patocka <mpatocka@redhat.com>

The patch 042da426f8ebde012be9429ff705232af7ad7469
("scripts/setlocalversion: simplify the short version part") reduces
indentation. Unfortunatelly, it also changes behavior in a subtle way - if
the user has empty "LOCALVERSION" variable, the plus sign is appended to
the kernel version. It wasn't appended before.

This patch reverts to the old behavior - we append the plus sign only if
the LOCALVERSION variable is not set.

Fixes: 042da426f8eb ("scripts/setlocalversion: simplify the short version part")
