[Bug 923430] [NEW] pkgstripfiles: md5sum incorrect when doc dir is a symlink

[Felix Geyer]

Public bug reported:

pkgstripfiles doesn't update the md5sum if /usr/share/doc/$pkg is a
symlink to another dir inside the same pacakge.

For example in perl-base contains the following files:
-rw-r--r-- root/root       163 2011-11-28 20:05 ./usr/share/doc/perl/Documentation
-rw-r--r-- root/root      1483 2011-11-28 20:05 ./usr/share/doc/perl/README.Debian
-rw-r--r-- root/root     87099 2011-11-28 20:05 ./usr/share/doc/perl/copyright
-rw-r--r-- root/root     19009 2011-09-26 09:44 ./usr/share/doc/perl/AUTHORS.gz
-rw-r--r-- root/root      3329 2011-12-16 12:38 ./usr/share/doc/perl/changelog.Debian.gz
lrwxrwxrwx root/root         0 2011-12-16 12:38 ./usr/share/doc/perl-base -> perl

pkgstripfiles reports:
> pkgstripfiles: Truncating usr/share/doc/perl-base/changelog.Debian.gz to topmost ten records

So it modifies usr/share/doc/perl-base/changelog.Debian.gz which really
is usr/share/doc/perl/changelog.Debian.gz and thus tries to update the
wrong file in md5sums.
