* doc/dejagnu.texi: Clean up whitespace. Some indented examples

	were changed to use the Texinfo '@ ' command (yes, a space
	character) to preserve correct indentation.  The '@ ' command is
	treated as a single space by Tex and makeinfo, but prevents Emacs
	from complaining about indentation using spaces instead of tabs.
