avoid space-tab

I'm applying this patch, because in the past, I have inadvertently
corrupted files when emacs whitespace mode decided to be 'helpful' and
collapse space-tab into plain tab.  Thus, when writing portable sed
expressions, a good rule of thumb is to use tab-space when searching for
either form of whitespace.

        * gnulib-tool: Rearrange space-tab sequences, since some editors
        like to eat them.

Don't work too hard, make some time for fun as well!
