[PATCH 2/2] po: Update Japanese translation style.

[Akihiro Sagawa]

Follow recent Microsoft Japanese Style Guide, especially Katakana
prolonged sound mark. As of 2008, they followed the June 1991 Cabinet
Notification on Loanword Orthography. It states prolonged the sound
mark should be used for long vowels when English original terms have
final -er, -or, -ar, in general.
