This patch switches to 'eval' here because it is the first time
'opts' occurs. However, I agree that it might be confusing that
'opts' wasn't already added to the 'do_pick' lines by 20/23. By
"trigger" you mean that this commit is the first to actually fill
'opts' with contents? I will move these changes to 20/23 then.

At least if we can assume that it is really a SHA-1 object name. As
such it does not contain characters interpreted by the shell, like
backslashes, quotes or whitespace.

The ones I had in mind are attached below the scissors line. The
current reroll fails the authorship checks and the 'git rebase
--continue' test cases. As the necessary changes would obfuscate this
sub-thread, they will be included in the next reroll.
