Using tramp-log-to-file variable with -Q

[Mikhail P]

Hi, I am trying to use loggin to a file feature. To do so I cloned and 
compiled tramp from source. Then I try to run

|~/bin/emacs -Q -l tramp --eval="(progn (add-to-list 'load-path 
\"/path/to/elisp/dir/tramp\") (require 'tramp) (setq tramp-verbose 10) 
(setq tramp-use-ssh-controlmaster-options nil) (setq tramp-debug-to-file 
t))" |

Running |M-x locate-library |gives the correct path to compiled tramp, 
not the sytem-wide one. However |C-h v tramp-debug-to-file| does not 
give anything. I see tramp debug buffers but nothing in /tmp (which is 
the temporary-files-folder). Everything works if I run it without |-Q 
...| i.e. with evaluating my .emacs file.

Thanks,

Mikhail
