Not sure what *he* means but I can guess: mysql has various options to 
call mysql without formatting  output or with a special way of 
formatting output when used from commandline/script. To relate this to 
Bacula: list media  scripted through bconsole: echo "list media" | bconsole
This produces a list of media formatted in an ascii-table with columns, 
fields etc marked up by "+" ,"-" and "|" characters.
Comparing this to mysql again: mysql allows the removal of 
column/field-names and other layouting. bconsole does not. (see man mysql)
This results in the need of getting rid of those from within the script. 
Fine if you are using perl, python, php etc but a bit more troublesome 
if you are scripting in Bash. (cut, grep, awk, sed can help of course). 
So the point being: bconsole's output must be stripped on every occasion 
which leads to more coding in scripts. Depending on the scripting 
language this is hard or easy but needed nevertheless.
