Fix 2011-12-03 regression. The freeform directive code

relies on lazy_str_get_trailing_list and the behavior
of that function changed because (split-str "" any-separator)
changed from returning nil to returning the empty string.
The resulting behavior change of lazy_str_get_trailing_list was later
described in the documentation, thereby codifying it.

This patch changes the lazy_str_get_trailing_list behavior,
which is poor, and causes infinite looping. We do not want
an extra empty string prepended, because it looks like
a spurious line.

* lib.c (lazy_str_get_trailing_list): if split_str produces
a the list (""), then just return the unmaterialized list from
the lazy string without prepending that one-element list to it.

* txr.1: Updated documentation for lazy-str-get-trailing-list.
