- better recognition of invalid config files
- general polish of error messages
- hkd follows the rule of silence
- when using -v the correct key names are shown
- commands in config files can be multiline (using \\n)

@ -89,10 +89,6 @@ This is a valid config file example
.PP
Known bugs are:
.IP -
Commands in the config file cannot be multiline
.IP -
Invalid config files are not detected properly, or at least not explicitly
.IP -
Child processes
are waited at program exit possibly causing the process tree to hang as there is
no real child process control
