org-clock misleading description for a prompt option

[Dmitrii Korobeinikov]

Hi!

When you run org-clock-in and then restart emacs, clocking in again
will show a prompt asking what to do w/ the unfinished entry. "i"
means "ignore this question; the same as keeping all the idle time".
However, a new entry is created if this is chosen without doing
anything about unfinished one. Keeping all the idle time w/ "k"
updates the unfinished entry before starting a new one. "i" doesn't do
that, so the description seems a bit misleading.

Best,
DK
