Granted.  But it doesn't make the code you showed less a fence-post
error :-).

Note, that's mostly for streams, and moreso for streams of text.  At
least in my area of experience...

Oh, absolutely.  What I wanted to point out is that there is a BIO
that uses file descriptors, which makes the need for a flag to
bss_file.c completely needless and one complication too many.  To
solve said problem, one should use the file descriptor BIO instead of
the stream BIO...
