A userscript that adds autocomplete search filters to GitHub

• Searching on GitHub is complicated, and there are over 50 filters to choose from. This userscript makes them a little easier to use.
• Search filter information obtained from the pages listed on https://help.github.com/categories/search/.
• If something isn't working, please review GitHub's search documentation linked above.
• Autocomplete searchs are applied to the following search inputs:
  • All pages on in the github domain with a search bar in the header.
  • https://github.com/search/
  • https://github.com/search/advanced
  • https://github.com/:user/:repo/issues
  • https://github.com/:user/:repo/pulls
  • https://gist.github.com/search
  • https://gist.github.com/search?q=css (added v0.1.5)
• To use:
  • Enter ? to get a full list of filters.
  • Press Enter, or click on the filter to choose it.
  • Enter the search term, or press → (right arrow) to open up a secondary list of terms & examples.
• NOTE: Issues do occur when using this userscript along with the Awesome Autocomplete for GitHub browser addon/extension:
  • The popup for this userscript overlaps the Awesome Autocomplete's popup.
  • Pressing Tab or Enter to select a dropdown item in this userscript's dropdown will also select Awesome Autocomplete's current selection and jump to that page. To bypass this problem, click on the selection using your mouse.
• Click this link to install from GitHub; or, install from GreasyFork or OpenUserJS.
