rustc broken pipe panic when I piped a wrong command

[lilianmoraru]

I was trying to get the version of the rust compiler I have:

rustc -V | cut -d '\(' -f 2 | cut -d ' ' -f 1

The issue is obviously in \( (was thinking regex) which should be swapped with (.
And yes, it's a "broken pipe" but I've never seen an application react like this to a wrong command being piped(And it's not rustc who receives something from the pipe, it's another application).

cut: the delimiter must be a single character
Try 'cut --help' for more information.
error: internal compiler error: unexpected panic
note: the compiler unexpectedly panicked. this is a bug.

I believe this is a dupe of #14505, so closing in favor of that, but thanks for the report!
