The bad part is the pattern is very weak, just 16 bits of a file are
considered enough to terminate the detection process - in general I try
to find at least 33 identifying bits. This can be improved by
re-ordering the rules, I'll bring this upstream. But for the moment
disabling such an error-prone pattern is the way to go.
Afterwards:
file-testsuite-data.git/debian-bugs/913867/csitt12.tfm: TeX font metric data
(TeX cs typewriter text)
file-testsuite-data.git/debian-bugs/913867/csitt8.tfm: TeX font metric data
(TeX cs typewriter text)
Version 1:5.38-1 will hit experimental very soon (hours - I'm still in
the middle of regression tests).

Excuse my blindness, do you want this sniplet become part of
file/libmagic? If yes, it should see some improvement first (just 17
identifying bits, see above).
