Hmmm... if the first link is correct I don't think this is something to be concerned about. Wikipedia says "Mac OS X 10.0 was released on March 24, 2001".

It sounds like there may be (or have been) a distinction between native app behavior vs unix/shell on MacOS. But I'm not in a position to test that.

Cameron (or anyone else on MacOS), can you confirm ':' is allowed for files on your system, especially those created from a shell or launched by Mutt via mailcap?

There may be security issues with some programs. The following one
is fixed, but there may still be similar ones around for programs
written in Perl.

Wow! Well that's just terrifying. I'm pretty sure I've taken advantage of that shortcut in the past and had no idea it would re-evaluate the filename. A very good argument to keep the sanitizer in place. Thank you again.
