Title: Break up tab boundary by space not by word

Current behavior: if you have this: `hello world[tab]`
the tab will select `world` as the prefix to lookup tab triggers for because it's the current word.
My modification does't look at the current word but instead looks backwards until it finds a space, and uses that as the prefix e.g `hello @world[tab]` would use `@world` as the prefix
