examples: add empty lines

Browse Source 
Currently the examples are too dense, let's put empty lines where
'#line' would be issued.  And also remove some spurious empty
lines (remains from @group, @end group, etc.).

* examples/extexi: Do that.
* examples/local.mk (extexiFLAGS): Rename as...
(EXTEXIFLAGS): this.
