Yes, please. I'd prefer a second --exclude option here instead:

        @grep -E '[ ]   ' --exclude=$(srcdir)/lib/regex.c               \
                --exclude=$(srcdir)/m4/lib-*.m4                         \
                $(srcdir)/{lib,src}/*.[chly]                            \
                $(find -name Makefile.am) &&                            \
          { echo '$(ME): found SPACE-TAB sequence; remove the SPACE'    \

When I set IFS to a value, it's totally natural that space comes first,
    1. <space> is more important than <tab>,
    2. the default value of IFS in the POSIX spec
       lists <space> before <tab>.

I see why your target 'sc_space_tab:' can be useful if you use Emacs and
don't have tabs turned off by default; but that not the case for the ,m4
files I maintain.
