 --bisect::
        Limit output to the one commit object which is roughly halfway
        between the included and excluded commits. Thus, if 'git-rev-list
-       --bisect foo ^bar ^baz' outputs 'midpoint', the output
-       of 'git-rev-list foo ^midpoint' and 'git-rev-list midpoint
-       ^bar ^baz' would be of roughly the same length. Finding the change
+       --bisect foo {caret}bar {caret}baz' outputs 'midpoint', the output
+       of 'git-rev-list foo {caret}midpoint' and 'git-rev-list midpoint
+       {caret}bar {caret}baz' would be of roughly the same length.
+       Finding the change
        which introduces a regression is thus reduced to a binary search:
        repeatedly generate and test new 'midpoint's until the commit chain
        is of length one.
