Re: Makefile rules indentation

Oops, this broke "make syntax-check".

  maint.mk: found TAB-8-space indentation
  make: *** [maint.mk:1192: sc_makefile_TAB_only_indentation] Error 1

This "prohibit space after TAB in Makefiles" rule makes no sense to me.
It is "TAB after space" that usually causes editing mistakes and
undesired diffs between revisions, not "space after TAB".

This rule was imported in gnulib's maint.mk in 2009, from coreutils. But like
any syntax-check rule, it can be disabled.

Do you prefer to keep it enabled in poke (and force mixed TAB+TAB+space
indentation in some Makefile.am lines), or do you prefer to disable it?
