Martin Povišer e3709ce776 passes: show: Fix portbox bit ranges in case of driven signals 
When the 'show' pass generates portboxes to detail the connection of
cell ports to wires, it has special handling of signal chunk
repetitions, but those repetitions are not accounted for in the
displayed bit range in case of cell outputs. Fix that, and so bring it
into consistence with the behavior on cell inputs.

So, taking for example the following Verilog snippet,

  module DRIVER (Q);
     output [7:0] Q;
     assign Q = 8'b10101010;
  endmodule

  module main;
     wire w;
     DRIVER driver(.Q({8{w}}));
  endmodule

make the show pass display '7:0 - 8x 0:0' in the driver-to-w portbox
instead of '7:7 - 8x 0:0' which it displayed formerly.

KrystalDelusion 9465b2af95 Fitting help messages to 80 character width 
Uses the regex below to search (using vscode):
	^\t\tlog\("(.{10,}(?<!\\n)|.{81,}\\n)"\);

Finds any log messages double indented (which help messages are)
and checks if *either* there are is no newline character at the end,
*or* the number of characters before the newline is more than 80.

Jannis Harder fc65ea47df select: Fix -assert-none and -assert-any error output and docs 
Both of these options consider a selection containing only empty modules
as non-empty. This wasn't mentioned in the documentation nor did the
error message when using `select -assert-none` list those empty modules,
which produced a very confusing error message complaining about a
non-empty selection followed by an empty listing of the selection.

This fixes the documentation and changes the `-assert-none` and
`-assert-any` assertion error messages to also output fully selected
modules (this includes selected empty modules).

It doesn't change the messages for `-assert-count` etc. as they don't
count modules.
