Follow-up Comment #17, bug #51871 (project octave):
Item # 1: Will need to fix octave_read_fp_value in order for sscanf to pass
Item # 2: Comment processing should be kept. First, because we need to be
Matlab-compatible. Second, because if you just have raw numbers in a file it
can be super confusing. It is far better to be able to add a few lines at the
top of the file saying what the data is, when it was collected, what the
format is, etc.
Item # 3: I don't think we need to support a bare '\r' line ending. Looking
at the Newline page on Wikipedia (https://en.wikipedia.org/wiki/Line_endings)
there are only a few systems that use '\r' alone
CR: Commodore 8-bit machines, Acorn BBC, ZX Spectrum, TRS-80, Apple II
family, Oberon, the classic Mac OS, MIT Lisp Machine and OS-9
None of these are very popular anymore, and if necessary one can use Perl to
transform the line endings before processing with Octave.
