Details:

Prompted by this question on stackoverflow:
https://stackoverflow.com/q/63325950/4183191

Steps to reproduce:
Step 1: Create the following script called myfunctiondefs.m


1;
function f1(); disp('hello from f1'); endfunction
function f2(); disp('hello from f2'); endfunction


Step 2: Create script myscript.m in the same directory


myfunctiondefs
f1()
f2()


Step 3: Open myscript.m in the octave GUI editor, run it once to generate the
function definitions in the current session, and then highlight "f2" with the
mouse, right-click, and select Edit f2 from the context menu.

Expected outcome: A generated f2.m file in the user's home folder, i.e. the
same as what would have happened if one manually typed "edit f2.m" in the
terminal.

Observed outcome: 
 - In octave v5.1.0: A popup window saying "f2 is a built-in, compiled, or
inline function and cannot be edited".

 - In octave v5.2.0: An empty, nameless m-file (in other words, a file called
".m" is created in the current directory).

Clearly there's a regression bug between v5.1.0 and v5.2.0. 

However, the bigger question is, when a name in the GUI editor is a reference
a command-line function, which doesn't right-clicking and selecting to edit it
behave the same as the equivalent "edit" command?
