Actually, this particular path is automatically modified by setup.rb.
Special provisions need to be taken in order to make sure the hashbang
line stays the same. Either you can just be careful when committing,
or you can have your build-script retain the old version of the
binary. For example, in ttime, I have the following rake task in place
(it's called by the debuild task)

  # Debuild with proper backup and restoration operations
  def safely_debuild(debuild_opts = "")
    # Save bin/ttime, as setup.rb modifies the shebang and mode
    tempd = `mktemp -d`.chomp
    FileUtils.copy("bin/ttime",tempd)

    begin
      `debuild #{debuild_opts}`
    ensure
      FileUtils.move(File::join(tempd, "ttime"), "bin/")
      Dir::rmdir(tempd)
    end
  end
