Description:
I added a my.ini file to my MySqlServer80 subfolder to modify the cli prompt like so:

[client]
prompt=\\u@\\h [\\d]>\\_

When I attempt to dump any databases from the command line i get the following error: [ERROR] unknown variable 'prompt=\u@\h [\d]>\_'.

if I comment out the prompt definition;
#[client]
#prompt=\\u@\\h [\\d]>\\_

I am able to dump ddatabases.

How to repeat:
add the following to your copy of my.ini:

[client]
prompt=\\u@\\h [\\d]>\\_

open windows cmd window and attempt to dump a database

c:\mysqldump -uroot -p my_sample_database > my_sample_database.dump
