Re: [Iverilog-devel] Small stuff

Here's another one:

`define \A foo

module `\A;
  initial
    $display("%m: Ok");
endmodule
this code doesn't work on any of the simulators on EDA Playground
(https://www.edaplayground.com/x/6yZJ). However, the LRM seems pretty
clear that it should:

text_macro_definition ::= `define text_macro_name macro_text
text_macro_name ::= text_macro_identifier [( list_of_formal_arguments )]
text_macro_identifier ::= identifier
identifier ::= simple_identifier | escaped_identifier

In other words, a text macro name can be an escaped identifier, but
no-one seems to support this. Xcelium, at least, just creates a macro
named 'A'.
