Since `do_pick` might be executed in a sub-shell (a modified author
environment for instance), calling `die` in `do_pick` has no effect but
exiting the sub-shell with a failure exit status. Moreover, if `do_pick`
is called while a squash or fixup is happening, `die_with_patch` will
discard `$squash_msg` as commit message. Indicate an error in `do_pick`
using return statements and properly kill the script at the call sites.
Remove unused commit message title argument from `do_pick`'s signature.
