The patch that allows "git bisect skip" to be passed a range of commits using the "<commit1>..<commit2>" notation is flawed because it introduces a regression when it was passed a simple rev or commit. "git bisect skip <commit>" doesn't work any more, because <commit> is quoted but not properly unquoted. This patch fixes that and add tests cases to better check when it is passed commits and range of commits. While at it, this patch also properly quotes the non range arguments using the "sq" function.
