I'm not sure I agree. Why would:

$$(ECHO) -n '$$($1_OVERVIEW_TEXT)' 

be better than

$$(PRINTF) "%s" '$$($1_OVERVIEW_TEXT)' 

?

We're kind of squabbling over details here, and it really doesn't matter as much, but I don't think there is really anything to gain by going down that route. If nothing else, `echo -n` seems like less widespread knowledge (Erik didn't know, I knew but had forgot since I never use it). In contrast, I believe the printf syntax is a bit more well known.

But sure, I can use `echo -n` instead of `printf` where possible. Just give me one good reason why.
