Details:

The output formatting can change and vary. But it has nothing to do with the
back-end core of the smart suggestion procedure. So, we can track and discuss
more about the output formatting here, and leave the other parts to task
#15799.

I have started this thread on stackoverflow: Is it possible to categorize the
bash autocomplete output? <https://stackoverflow.com/q/66483519/6474744>

However, we might be able to colorize the output as Mohammad suggested
<https://savannah.gnu.org/task/?15799#comment22> as well. These links can help
for a start:

* Using colors with printf <https://stackoverflow.com/a/5412776/6474744>
* Bash tips: Colors and formatting (ANSI/VT100 Control sequences)
<https://misc.flogisoft.com/bash/tip_colors_and_formatting>
* How to Customize Bash Colors and Content in Linux Terminal Prompt
<https://www.tecmint.com/customize-bash-colors-terminal-prompt-linux/>

I tried using them. But there is a problem. It looks like the 'COMPREPLY'
values are treated as literal strings. That is why the ANSI color coding does
not work as expected. There might be a workaround.
