And the overall feature seems severely under-documented... Honestly, I barely 
understood your explanations...

Maybe expecting to have abbrevs work way was a mistake, but it does not seem 
possible to have (easy...) arbitrary string expansion in out-of-the-box-emacs 
without abbrevs.

Would there be another more idiomatic way ?
I know about assigning key shortcuts to arbitrary string insertion, but that 
needlessly fills the keymaps with shortcuts that could be put to better use 
*and* the combination would be longer to enter than a normal abbrev...

I'll try that and will report. Thank you !
