git-filesync 0.23.1

Patterns of a linked directory always shell-quoted in .git-filesync

Changes:

• include / exclude are written shell-quoted throughout, like git-assetsync
  writes its lists: include = '*.c' instead of include = *.c (also for
  patterns with ! or non-ASCII characters).

Compatibility:

• Existing .git-filesync files read the same; their values keep their form
  until the patterns change.
