Code review

[Peter Humphrey]

Hello list,

Is this the proper place to point out any oddities I may find in trying to 
make sense of KMail code? Some questions will no doubt be newbie grade, 
becuase I've never looked at C++ before. I've extracted and configured the 
source under ~/projects/myKmail/kmail-19.04.3.

The first thing I've noticed is that the file kmail-19.04.3/po/en_GB/
akonadi_mailfilteragent.po contains lots of four-line stanzas like this:

#: filterlogdialog.cpp:102
#, kde-format
msgid "Share..."
msgstr "Share..."

But one of them has an extra line:

#. i18n( "" ) );
#: filterlogdialog.cpp:136
#, kde-format
msgid "Log filter &rule evaluation"
msgstr "Log filter &rule evaluation"

First, what does the i18n line do, and second, why does it have an extra 
closing bracket? Could anything go wrong because of this?
