I believe that it misses the point. It is still not clear that the echo
command doesn't behave as one would expect for a few edge cases.
Maybe something like this would be closer to what I'm trying to express:
NOTE: printf(1) is a preferred alternative, which doesn't share echo's
inability to handle edge cases.
I'm not sure that just mentioning "edge cases" will remind people either
that they are falling into such particular edge case.
Therefore, I'd prefer Padraig's shorter sentence: it expresses the matter
positively while the latter proposal tries to explain via negative wording.
If we want to be more explicit, then we'd have to name examples where
printf(1) is superior to echo(1) - or the shell's echo builtin.
But IMO the whole point is two-fold: if someone doesn't have enough experience
to understand the edge cases, then eventually the usage of printf with the
often complex format specifiers is also too much.
Finally, I think Padraig's suggestion had the best tradeoff between pointing
out the matter and getting too much into details.
