7" This script defineds functions and key mappings for Tab completion in
8" searches.

10" Help:
11" This script catches the <Tab> character when using the '/' search
12" command. Pressing Tab will expand the current partial word to the
13" next matching word starting with the partial word.
14"
15" If you want to match a tab, use the '\t' pattern.
