[Octave-bug-tracker] [bug #59706] Avoid "canonicalize_file_name" on Windows

[Rik]

Follow-up Comment #14, bug #59706 (project octave):

@Markus: I think of resolving symbolic links as being part of either making
the path absolute, or checking whether the file exists.  I believe we are in
complete agreement.

Since it is going to be a long while before C++17 is supported by Octave we
might look at improving Octave's own functions in this regard.  These are
located in liboctave/utils/oct-env.[h|cc].

In particular, it's likely that Octave is just taking a shortcut and scanning
for '.' or '..' only at the front of the string.  We could extend the
algorithm to search through the entire string and eliminate all such
instances.
