top: touch up a few miscellaneous nls related comments

Some recent nls work on that pmap program necessitated
a return to nls translation file creation for testing.

As it turns out, my skills used in pseudo-translations
had become rusty and some newer LC_MESSAGE directories
may have been introduced since last needing the topic.

This patch just updates some programmer notes to agree
with this most recent effort and for future reference!
