'msgid' and 'msgstr' entries do not both end with '\n'

When in the locales directory, I check all po files with msgfmt, redirecting stderr/stdout to a file so I can properly grep for a fatal error:

$ for i in */*/*.po; do msgfmt -c $i; done &> x
$ grep -B1 fatal x
ca/LC_MESSAGES/plone.po:10856: 'msgid' and 'msgstr' entries do not both end with '\n'
msgfmt: found 1 fatal error
--
de/LC_MESSAGES/plone.po:14240: 'msgid' and 'msgstr' entries do not both end with '\n'
msgfmt: found 3 fatal errors
--
it/LC_MESSAGES/plone.po:13549: 'msgid' and 'msgstr' entries do not both end with '\n'
msgfmt: found 3 fatal errors
--
ru/LC_MESSAGES/plone.po:13549: 'msgid' and 'msgstr' entries do not both end with '\n'
msgfmt: found 1 fatal error
--
sl/LC_MESSAGES/plone.po:13513: 'msgid' and 'msgstr' entries do not both end with '\n'
msgfmt: found 1 fatal error
--
zh_TW/LC_MESSAGES/plone.po:13512: 'msgid' and 'msgstr' entries do not both end with '\n'
msgfmt: found 2 fatal errors

There are various warnings as well. But the fatal errors could mean that Plone fails to parse some po files at startup, causing missing translations.

This reminds me, it might be nice to have a few checks using GitHub actions.
