Highlight on key press option

[unblevable]

Issue #2.

Added option g:qs_highlight_on_keys:

" Trigger a highlight for all character motions
g:qs_highlight_on_keys = ['f', 'F', 't', 'T']

" Trigger a highlight for just 'f' and 'F'
g:qs_highlight_on_keys = ['f', 'F']

Here is an updated task list:

• [x] Trigger a highlight on any of f, F, t or T.
• [x] Trigger only a forward highlight on f and t and only a backward highlight on F and T.

• [x] After executing a character motion, trigger an "extra" highlight for the target character only if it originally had a second-occurrence highlight.

  (I don't have access to my computer with screen capture software at the moment, so you're going to have to try this pull request out yourself if the description wasn't clear for you).

  After a lot of fiddling around, I've decided that this is probably the best solution for quick-scope:

  • It keeps the plugin simple: user locks eyes on a word ⇨ user targets highlighted character in that word ⇨ character in that word remains highlighted until the user moves to the word (or cancels the highlight).
  • This option is for users who felt that quick-scope's default behavior was too distracting, and in my opinion, this is a pretty un-distracting enhancement.
  • It mirrors the default behavior of quick-scope in a way.
• [x] If g:qs_highlight_on_keys is enabled, avoid using autocommands if possible.
• [x] Keep the cursor visible during the character motion.
• [x] Add documentation to README and help docs.

When I hit f and then C-c, it says Type :quit<Enter> to exit vim in the Ex command line area and the characters continued to be highlighted even if I move to another line. Also, the cursor disappears sometimes afterwards and the cursor doesn't always update normally when it is visible. When I exit vim after doing that, the cursor is invisible in the terminal until I run reset (or reopen the terminal)

Thanks for catching that error...having a bug that also messes up your terminal session would have been pretty annoying.
