[Octave-bug-tracker] [bug #48351] make_absolute_filename should canonicalize absolute filename inputs

[Rik]

Update of bug #48351 (project octave):

                 Summary: make_absolute_filename should strip trailing file
separator characters => make_absolute_filename should canonicalize absolute
filename inputs

Follow-up Comment #5:

I pushed a change to make_absolute_filename here
(http://hg.savannah.gnu.org/hgweb/octave/rev/6e618b8277ad).

This fixes the issue with run.m, however, it still doesn't fix an input which
is already an absolute filename such as '///'.  In that case, do_make_absolute
uses do_absolute_pathname() to determine that it is already absolute so it
doesn't process it.  We could remove that check, but that might carry a
performance penalty.  While using gdb, I found that do_make_absolute is called
every time Octave returns to the command line.
