From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Stefan Reiter Date: Wed, 1 Sep 2021 16:51:04 +0200 Subject: [PATCH] monitor/hmp: add support for flag argument with value Adds support for the "-xS" parameter type, where "-x" denotes a flag name and the "S" suffix indicates that this flag is supposed to take an arbitrary string parameter. These parameters are always optional, the entry in the qdict will be omitted if the flag is not given.
