Bug#862827: licensecheck: MPL check too simple, causes false positives

[Axel Beckert]

Package: licensecheck
Version: 3.0.29-1

Dear Maintainer,

the attached file is reported by licensecheck as follows:

  /tmp/dns.h: MPL GPL (v2 or later) (with incorrect FSF address)

But the only line in which the string "MPL" appears is this line:

  #define DNS_SE_CHK_NOTIMPL  0x0008

(The original example with which I ran into that issue is
https://github.com/gamelinux/passivedns/blob/master/src/dns.h)

Please check at least that MPL is matched as word and not as simple
substring, i.e. "\bMPL\b" or similar. But preferable the check should be
still a little bit more sophisticated than that.
