-a prints unprintable chars when abbreviations are applied

[heasm66]

In disassembly (-a), @print and @print_ret prints unprintable characters (ascii 1) when printing a string containing an abbreviation.

206  +00092 <*> print        "w���"

This is because translate_text in text.c modifies the text_in parameter when applying the abbreviation by replacing the text that is being abbreviated with values of 1 instead of the characters.

The assembly are printed after the call to translate_text and is therefore mangled.

One easy fix would be to make a local undamaged copy of the text before the call to translate_text in assemblez_instruction and use it instead when printing tthe assembly.

Since this is for tracing, I think it's better to print an abbreviation marker. (I've tried hard to get rid of all the fixed-length string buffers!)

[heasm66]

That explains why I had a hard time finding any internal example for a short temp string...

The actual text isn't especially important so an abbreviation marker is perfectly fine.
