commit https://github.com/vim/vim/commit/36d7cd8965bc4027d420c7d70c56ac95d83d3bfa Author: Bram Moolenaar <Bram@vim.org> Date: Fri Jan 15 22:08:23 2016 +0100 patch 7.4.1099 Problem: It's not easy to know if Vim supports blowfish. (Smu Johnson) Solution: Add has('crypt-blowfish') and has('crypt-blowfish2').

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