[Qemu-devel] [PATCH] monitor.c: Fix infinite loop in monitor's auto-complete functionality

[Dimitris Karagkasidis]

The QEMU monitor enters an infinite loop when trying to auto-complete commands
that accept only optional parameters. The commands currently affected by this
issue are 'info registers' and 'info mtree'.
