bug#17639: new snapshot available: grep-2.19.12-96bd

grep-2.19 introduced a bug whereby certain regexps can
mistakenly match certain input lines. This is a big enough
deal that I'm going to release grep-2.20 in the next few days.
To prepare for that, here is a pre-release snapshot of the latest.
Please give it a workout and let us know how any testing goes.

** Bug fixes

  A command like echo aa|grep -E 'a(b$|c$)' would mistakenly
  report the input as a matched line.
  [bug introduced in grep-2.19]

** Changes in behavior

  grep --exclude-dir='FOO/' now excludes the directory FOO.
  Previously, the trailing slash meant the option was ineffective.
