[Octave-bug-tracker] [bug #62552] In-place operator spacing works for 'i' and 'j', but not other variable names

[Rik]

Update of bug #62552 (project octave):

                  Status:                    None => Confirmed              
                 Summary: Operator spacing works for i and j but no other
variables => In-place operator spacing works for 'i' and 'j', but not other
variable names

Follow-up Comment #2:

To make it even clearer, the normal failing case is


k = 0; k +=1


which issues an error because this looks like command function calling of the
function 'k' with string argument '+=1'.

The equivalent


i = 0; i +=1


does not issue an error and instead calls the in-place addition operator.

This might have something to do with i,j being complex constants. 
Incidentally, this is also an issue for 'I', 'J' which are also parsed as
complex constants.  In addition, 'i', 'j', 'I', 'J' are also functions and
that may be a further complication.
