merge: make messages translatable

These messages have been overlooked by check-code, because they start
with non-alphabet character (' ').

Making these messages translatable seems reasonable, because all other
'ui.note()'-ed messages in calculateupdates() are already
translatable.

This is also a part of preparation for making "missing _() in ui
message" detection of check-code more exact.
