pdb repeats w 0 on empty line when there are commands in cmdqueue

[gaogaotiantian]

Bug report

Bug description:

If you do a n ;; p 1 in pdb, the next time you entry an empty line (meant for repeat last command), it will repeat w 0 due to #119882. It's supposed to repeat p 1 (arguably n ;; p1 but we never do that). As user never inputs w 0 by their own, the current behavior might not be desired.
