Bug#1102659: vcsh: please make the build reproducible

[Chris Lamb]

Source: vcsh
Version: 2.0.10-0.1
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
vcsh could not be built reproducibly.

This is because the main vcsh script varies in its shebang depending
on the current shell:

  │ │ ├── ./usr/bin/vcsh
  │ │ │ @@ -1,8 +1,8 @@
  │ │ │ -#!/bin/bash
  │ │ │ +#!/bin/sh

I think the attached patch should fix it; a similar approach has worked
with other Autotools packages, although I have never managed to trace
exactly through the code how the _autodetection_ works.
