Backup files witilde suffix does not trigger the bug being discussed. It's *only* files paths where the tilde is surrounded on both by spaces (or on the right by the end fo the string) that trigger it. > path.expand("a~b") [1] "a~b" > path.expand("a ~ b") [1] "a /Users/gabrielbecker b" > path.expand("myfile.txt~") [1] "myfile.txt~" > path.expand("myfile.txt ~") [1] "myfile.txt /Users/gabrielbecker" All that said I'm really not interested in participating in a flame war over this. I gave my 2 cents as respectfully as I could, so as of now please consider my participation and interest in this thread closed.
