bisect: fix quoting TRIED revs when "bad" commit is also "skip"ped
When the "bad" commit was also "skip"ped and when more than one commit was skipped, the "filter_skipped" function would have printed something like: bisect_rev=<hash1>|<hash2> (where <hash1> and <hash2> are hexadecimal sha1 hashes) and this would have been evaled later as piping "bisect_rev=<hash1>" into "<hash2>", which would have failed. So this patch makes the "filter_skipped" function properly quote what it outputs, so that it will print something like: bisect_rev='<hash1>|<hash2>' which will be properly evaled later. The caller was not stopping properly because the scriptlet this function returned to be evaled was not strung together with && and because of this, an error in an earlier part of the output was simply ignored. A test case is added to the test suite. And while at it, we also initialize the VARS, FOUND and TRIED variables, so that we protect ourselves from environment variables the user may have with these names.
