When we prepend a single quote to our query in --exact mode, we are not
supposed to limit the scope of the new search to the previous
exact-match result.

Faster startup. Use internal bash globbing instead of external grep binary (adapter from Gentoo's `/etc/bash/bashrc` TERM checking). Insignificant on Linux, but on Cygwin this cuts startup time by 40 ms on my Core i7 laptop.

Fixes #548. Avoid using a subshell in _fzf_defc().

Based on the patch by Matt Westcott (@mjwestcott).
But with a more conservative approach:
- Does not use linearly increasing penalties; It is agreed upon that we
  should prefer matching characters at the beginnings of the words, but
  it's not always clear that the relevance is inversely proportional to
  the distance from the beginning.
- The approach here is more conservative in that the bonus is never
  large enough to override the matchlen, so it can be thought of as the
  first implicit tiebreak criterion.
- One may argue the change breaks the contract of --tiebreak, but the
  judgement depends on the definition of "tie".
