No, but you are not far from it :)
F is source file's name; L is line number.
But both control only *how* DBUG output is printed (what decorations),
they do not control *when* DBUG output is printed; that is controlled
with "d" (print when meeting a DBUG_PRINT statement), "t" (print
when meeting DBUG_ENTER/DBUG_RETURN), etc.
Try --debug=d:t:F for example.
I bet you have found the manual, but in case, it's in dbug/user.*
files in the MySQL source tree (user.ps for example).
