[PATCH 2/3] bisect: remove CR characters from revision in replay

["Carlo Marcelo Arenas Belón" <carenas@gmail.com>]

6c722cbe5a (bisect: allow CRLF line endings in "git bisect replay"
input, 2020-05-07) includes CR as a field separator, but doesn't
account for it being included in the last field, breaking when
running at least under OpenBSD 6.7's sh.

Read the revision into a raw variable and strip it of any possible
embeded CR characters, before use.
