PATCH: unambiguous string heuristic

[Sven Wischnowsky <wischnow@informatik.hu-berlin.de>]

With a match spec such as `r:|.=*' and trying `Zle/zle_t<TAB>' one
gets `Zle/zle_t.' (note the dot). This patch avoids inserting such
small unambiguous anchors if there are characters missing before them
(and they are at the end of the string, inside words older code takes
care of them).

 Sven
