Added .lst file creation directives

[icypawn]

• -u
• -U

   -L         Create verbose listing (expand REPT, MACRO)

-u will only expand macros (rept definitions are shown)... reduces .lst file size

 (without -U directive, -u keeps macro definitions shown)

-U will ONLY expand macro use; hides macro definitions and also runs -u flag

---

line 1687 is major change that runs listline depending on 5 flags

that line is simplified with boolean algebra :)

Note: running asm6f with all the listing flags will cause a -L lst file to be created, like Loopy's original design :)

  all lines we edited end with 0_0
		except: the 4 variables we created at the end of the variable list
				and line 1687... sorry.

  we is God, my heavenly father, and me :)

p.s. Koitsu encouraged me to submit these changes to your asm6f

YEAY, branch c69f34a has the change from line 1769... that line's | was changed to a + because that should eliminate all of the "possible" problems that may happen if insidemacro and insiderept are ever both nonzero.

I learned to always close the file before pushing something. And to never change anything because that will eliminate all comments. :(

branch ebde657 is pointless... I hadn't closed the asm6f.c so it didn't update.

My comments that got eliminated said something like:
Line 1687 is the heart of my changes. And... I can't remember right now.
final edit: those eliminated comments have been rewritten on branch c69f34a

freem, is there something else I need to do? I'm done with editing this commit. :)

[freem]

Is the fallthrough here intentional? (Or in other words, -u and -U are mostly similar, but -u doesn't set vacillatemacro)

[icypawn]

Yes the fallthrough on case U is intentional. (Just like loopy's -L -l fallthrough is intentional.) That's where that fallthrough idea came from; furthermore, the fallthrough on -U reduced the boolean algebra result on 1687. It is simpler and takes less lines of code. :) Both beneficial, for me at least. :)

[icypawn]

Yes that's intentional. :) Both -u and -U set needrept to 0 and set listfilename to true_ptr (if listfilename==true_ptr then asm6 creates a listing file... listfilename=true_ptr is also underneath -L and -l; after thinking about this for quite a while, it doesn't seem possible to conveniently have -L, -l, -U, and -u to use the same listfilename=true_ptr). However, -U also sets vacillatemacro to 1. The state of the flags needrept and vacillatemacro help the program to know how to branch after loading them in other places in this commit's code. I have a page of boolean algebra that verifies what you encounter when you run this commit. It does work freem.

The simplicity is purposeful. Personally, I didn't want to cause the user's computer to have to do an extensive amount of work compared to asm6.
