[PATCH 1/2] bisect: fix "git bisect skip <commit>" and add tests cases

[Christian Couder <chriscool@tuxfamily.org>]

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.
