Octave-7.0.0 (dev) on Windows does the same as Octave-5.1.0. So apparently it has been "fixed" or "restored".

Your other question, at least what I could make from it, seems logical at first sight. But then, how would you edit a command line function, which -as the name says- is defined using the command line?
Have you compared with Matlab?

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

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

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

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


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?
