[Simh] fprint_sym and parse_sym limitation

As currently defined, fprint_sym and parse_sym are invoked strangely when processing a register value. From looking at the code, I can see that for this case, the "addr" argument is set to the register radix, and SIM_SW_REG is set in the switches word. It may be desirable to format or parse

[Simh] Command processing -- abbreviations and VM-supplied commands

In doing a new simulator, I ran into an unexpected quirk of command parsing, in particular handling of VM-specific commands. The way it works is that a user command matches a command table entry if the user string is a prefix of the command in the table. And as soon as a match is found, the
