Fix invalid regular expression #156861
Empty parantheses are not supported in regular expressions on Darwin/macOS. The old regular expression produces an error during evaluation. This commit fixes that. Nix‘s `builtins.match` works with extend POSIX regular expressions. The specification for these regular expression states[^1] that the result for a left paranthesis immediately followed by a right paranthesis outside of a bracket expression is undefined.
