[PATCH] D66293: [lit] Check for accidental external command calls

[Paul Robinson via Phabricator via llvm-commits]

probinson added a comment.

IIUC this means if anyone tries to write a RUN line that pipes something to `diff` or `cd` or whatever, it would explicitly fail.  That's probably a good move.
I suspect that `:` is not a legal filename on Windows.  I'm not able to create such a file from the Windows CMD shell, and grepping the llvm and clang test suites for 'RUN:.* :' doesn't turn up anything that tries to use `:` as a command.  Maybe we should just eliminate that command?
