Here's a revised version of the search-plugin that Hans started:
* fixed problem with double results if a path dir was a subdir of another
* can search for phrases by using double quotes
* search for whole words or partial matches
* search for all or any terms
* better scrollbar (ttk::scrollbar)
* Google-style search history (press the down-arrow in the search box to
make it appear, Escape to make it go away)
* hacked a proc to get <control-delete> to delete previous word
Requires tcl/tk 8.5. Works best with the revised pddp docs (i.e., if you
want to search by the keywords listed you'll need them).
