I bootstrap native build environments and run 'em under qemu, therefore  
this is sufficient for my needs.

My intended gripe was more along the lines of "autoconf is useless and  
making it _more_ complicated doesn't improve matters, the correct  
response to stroppy FSF code is almost always ripping it out". But  
that's a largeish tangent for this thread/list.

Utterly doesn't matter.

I implemented -e in busybox and toybox. (And the toybox one understands  
"--".) Considering I'm running it in an environment I built from source  
using known package versions...

If you're really going to care about that you need -print0 because a  
filename can have an embedded newline in it, but none of the packages  
I've ever encountered do that; the paths it's processing are  
package-relative.

(I'd ask why you're trying to prove you're a better programmer than  
other people instead of trying to prove you're a better programmer than  
the computer, but I honestly don't care. This is the dropbear list,  
this tangent is not about dropbear...)
