patch 8.0.0630: it is not easy to work on lines without a match commit https://github.com/vim/vim/commit/f84b122a99da75741ae686fabb6f81b8b4755998 Author: Bram Moolenaar <Bram@vim.org> Date: Sat Jun 10 14:29:52 2017 +0200 patch 8.0.0630: it is not easy to work on lines without a match Problem: The :global command does not work recursively, which makes it difficult to execute a command on a line where one pattern matches and another does not match. (Miles Cranmer) Solution: Allow for recursion if it is for only one line. (closes #1760)

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