commit https://github.com/vim/vim/commit/ca8b8d6956dd881de6446fc32c38e817a364a6cc Author: Bram Moolenaar <Bram@vim.org> Date: Thu Nov 17 21:30:27 2016 +0100 patch 8.0.0092 Problem: C indenting does not support nested namespaces that C++ 17 has. Solution: Add check that passes double colon inside a name. (Pauli, closes https://github.com/vim/vim/issues/1214)

#! /bin/sh

# which.sh -- find where an executable is located.  It's here because the
# "which" command is not supported everywhere.  Used by Makefile.
