Follow-up Comment #22, bug #51871 (project octave):

>> The obvious test would be to peek into the first, say 255 bytes, of the
file and see if we find a line ending. 

What I suggested #21 is meant to find out that line ending.  Anyway, I should
have pointed out in the previous post that my thinking was along the lines of
sed, grep, wc (which can tell one the number of lines in a file).  That is,
these character-by-character, causal, in-line operations that don't rewind
file pointers or string pointers are all rather fast.
