I think a specialized editor is all it would take. Edsharp
(http://www.empowermentzone.com/edsetup.exe) has a way of converting
braced code into Pythonic indents and colons, but you then have to
manage two sets of files, the braced code and the indented code.
Perhaps such an editor is a future project for me...

Tabs are worse because, for some very annoying reason, my reader reads
both hard returns and tabs as the word "blank". That means that I have
no way of knowing when I am reading a tab and when I have gone to a
previous line. Spaces are the only viable option.
Thanks for the script; if I have to attach code in the future, I will
try to remember to run the file(s) through it for easier reading. I
can also make your script remove the #end... comments, since I know a
lot of people do not like them either.
