[Octave-bug-tracker] [bug #35852] fscanf does not read full file

[Jordi Gutiérrez Hermoso]

Follow-up Comment #21, bug #35852 (project octave):

There are a bunch of other locations in lo-utils.cc that we call
istream::putback more than once, more than the ones you've patched about. It
seems awkward to "fix" all of those, when I can't even find a clear indication
that istream::putback shouldn't be called this way. Can you find a C++
reference, not C, that says we're doing something wrong, or how should we do
this correctly?

I am still probably going to apply your patch, but I want to know what the
right thing to do here is. As far as I can tell, we're calling
istream::putback correctly.
