That is because the server sending the file said it was text/plain.

For this example the interesting question is simply "what type is the server
labeling this file as?" You can check like this:

$ telnet fisica.fc.ul.pt 80
HEAD http://fisica.fc.ul.pt/~jbatista/tstamp.c HTTP/1.1
Host: fisica.fc.ul.pt

HTTP/1.1 200 OK
