Right now the printf(3) family of manpages make no reference to errno.
Glancing at __vfprintf, it appears that most of the erroneous paths do
set errno.
Should the manual be amended to reflect this behavior, so that users
have a documented way to determine the cause of failure in such cases?

Performance critical? Well, given the pathetic

If the file is written out, the file is destroyed.
IMnsHO, that is fatally flawed.
Returning an error for an impossible character translation is specified
in the archaic version of the Unicode standard I read.
That is not useful in an editor.

Fix possible reads past the end of the buffer.
Found by random fuzz testing (zzuf). Without the fix the fuzzer crashes
in several seconds; with the patch, the fuzzer runs clean for hours.

I chose to keep the condition simpler and the existing constraints intact for
minimal impact, but I would agree it's better to consolidate with the existing
check.
Your diff looks good to me, +1.
Looking at the ed25519 code, these defines are unused. They appear to be unused
upstream as well (in djt's supercop ed25519/ref implementation), so maybe this
should be suggested there instead of deviating. Up to you.
