[Bug-tar] bug in bootstrap

[Eric Blake]

The nice addition of parsing ./.bootstrap during bootstrap to provide
canned command-line arguments has a slight flaw; patch below.

Also, in the eval that parses .bootstrap, "set --" is nonportable
(use "set dummy; shift" instead), and the eval is not robust to
characters special to the shell in $* (for example, you
have broken ./bootstrap --gnulib-srcdir='dir with space').  I wasn't
sure of how to patch that.
