Ghidra: Incorrect Z80 instruction LD A,HL in exported text/assembly files.

[Colpocorto]

To Reproduce
Steps to reproduce the behavior:

1. Create a Project
2. Click on Create Tool
3. Select Ghidra Core
4. On the newly created tool, click on File... and Import File.
5. Select any Z80 executable file (e.g. a vintage arcade ROM file or a CP/M .com program).
6. Do a basic disassembling process and spot a LD A,(HL) instruction.
7. Now click on File... Export... and create an output file in ASCII or HTML format.
8. Open the new ascii or html format file and inspect the LD A,(HL) instruction: it is written as LD A,HL (without parenthesis), which is not a valid Z80 mnemonic.

Expected behavior
All occurrences of LD A,(HL) must use parenthesis.

Environment (please complete the following information):

• OS: Windows 7 64bit / Linux 64bit
• Java Version: 11
• Ghidra Version: 9.0.4

The problem isn't just with LD A, (HL) or just with the exporter. I see it with many Z80 instructions: SBC A, (HL), LD (BC), A, etc. The Disassembled View plugin mangles the parentheses as well (but only chops off one of them).

I reported this bug more than one year ago; it has not even been assigned yet. Open-source brings many benefits, they said...
