ps columns get unaligned for longer values

ps looks ugly in locales where strftime %b is not exactly 3 bytes, i.e compare:

➔ LC_ALL=C date +%b
Jun
➔ LC_ALL=et_EE.utf8 date +%b
juuni
➔ 

and now ps:

➔ ps --version
procps-ng version 3.3.10
➔ LC_ALL=et_EE.utf8 ps u

also seems VSZ and RSS cause similar issues for larger values
