Severity: minor
The algorithm which make iteration on each rule does not work always
the same. I observed this with the two following examples:
0 string/cb \<?xml XML document text
0 string \<?xml\ version " XML
0 string \<?xml\ version=" XML
>15 string >\0 %.3s document text
gives XML 1.0 document
This mean that rule 3 and 4 override rule 1.
when
0 string Rar! RAR archive data,
>44 byte x v%0x,
>35 byte 0 os: MS-DOS
>35 byte 1 os: OS/2
>35 byte 2 os: Win32
displays
RAR archive data, v1d, os: Win32.
This mean that rule 5 does not override rules 1 and 2.
Why does not it behave the same way?

Please read the man page magic(5). The way the rules work is explained
there. Basically, when a rule at level n matches, all the rules at level n+1
are tried. This means that only one top-level rule ever matches, but
multiple lower-level rules can match (for the given top-level match).
