Please allow m4 1.4.8-2 in testing

[Santiago Vila <sanvila@unex.es>]

Using 1.4.8-1:

$ m4 -- file-which-does-not-exist
Segmentation fault

Using 1.4.8-2:

$ m4 -- file-which-does-not-exist
m4: file-which-does-not-exist: No such file or directory

The fix is one line, and upstream confirms it's correct.
This is the complete diff between 1.4.8-1 and 1.4.8-2:
