[PATCH 4/5] remove shell function "spy"

[Paolo Bonzini]

This patch removes the shell function "spy" that was added a
few years ago.  It did help finding a couple of bugs, it has
made its time though.

2008-09-18  Paolo Bonzini  <address@hidden>

        * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Remove.
        (AS_INIT): Do not call it.
