Buglist for version 4.65

I don't love to tell you those bugs, but I think it's better than leaving you hanging.

1) ;~+ Comment bug:

	;~comment
	; I don't know how  to ~comment

but even worse:

	;~+
	No way! This is bogus!; I don't know how  to ~
	continue ; Pausing...

2) Procedure redefinition bug (wrong error message):

	circle2
	;  	[]
	doesn't like Unbound as input

circle2.lg is:

	to circle r
		arc 360 r
	end

3) Arcbug (arcbug.lg): on resizeing the screen some rabbish is drawn.

	to arcbug
		cs
		fd 400
		lt 180
		arc 15 100
	end

4) "=" bug (wrong error message):

	show a=1
	;  = didn't output to 	[]

5) another "=" bug:

	i1=0
	show i1
	Unbound

Workaround is adding a space after a symbol with numeric end:

	j1 =0
	show j1
	0

6) "+=" bug: the number input is not copied but changed.

	a=0
	b=a
	a+=1
	b
	1  ;-)

Workaround: use a=int for initialising when using "+="!

7) empty line "end" bug:

	to t
		pr 1234

	end


	end
	t defined
	t
	1234
	; I don't know how  to end  in t
	pr 1234 end

Workaround: don't use empty lines before "end".

9) setItem operator "a.b=c" bug:

	a=[]
	a.1=0

crashes the interpreter very badly.

10) ".="-bug:

	a.=1
	a  ;-)

prints a bad error message.

11) "Shell"-bug: the output is cluttered with empty lines.

12) "a -1 -bug:

	"a -1
	a  ;-)

should output like this:

	"a - 1
		[a - 1]
	 ;-)

13) "a=1e-6"-bug:

	a=1e-6
	; I don't know how  to 1e-6

Workaround is adding a space:

	a= 1e-6
	a
	1e-006  ;-)

14) "=="-bug:

	(1+1)==2
	; too much inside ()'s

Workaround is adding a space:

	(1+1) == 2
	true  ;-)

15) "1-.5"-bug:

	1-.5
	; not enough inputs to .

^Workaround is adding a space:

	1- .5
	0.5  ;-)

16) case ignored bug:

	pr "M 	;should print "M , not "m!
