MIME-type magic hierarcy

[Colin Bartolome]

I've got a similar problem. With rules like this:

0  string      DOC
 >144  string   JDASH    application/x-ichitaro4

I can make a test file that produces this output:

[user at host ~]$ file -im magic doc
doc: application/x-ichitaro4
[user at host ~]$

Then I can change the file so the DOC rule matches but the JDASH rules 
doesn't. Then I get this output:

[user at host ~]$ file -im magic doc
doc:
[user at host ~]$

Also note what happens when I add the -k flag, as it matches all the DOC 
rules but none of the continuations:

[user at host ~]$ file -rkim magic doc
doc:
-
-
[user at host ~]$

I think there should be a flag where if a rule's continuation doesn't 
match, nothing in the entire tree is printed and it just moves on. This 
file should just wind up as text/plain.

Please let me know if there's already an option for this.
