Excerpt from /usr/share/magic.mime:

--- snip ---
# msword: file(1) magic for MS Word files
#
# Contributor claims:
# Reversed-engineered MS Word magic numbers
#

0	string		\376\067\0\043			application/msword
0	string		\320\317\021\340\241\261	application/msword
0	string		\333\245-\0\0\0			application/msword
--- snip ---

The middle one of those matches the first six bytes of a powerpoint
file.  Whether it also might match the first six bytes of some msword
documents, I don't know.
