Except for the formatting, how far would this get you:
Code:
awk '
NR == FNR       {q = $1 "," $2
                 $1 = $2 = ""
                 T[q "," ++C[q]] = $0
                 next
                }
                {q = $1 "," $3
                 X = q "," ++D[q]
                 printf "%s\t",  $0
                 if (X in T)    print T[X]
                 if ($3 == "?") print "  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -"
                }
' file1 file2

Please note, that
Quote:
awk's behavior is to give precedence to the last line number in an array when one of its elements is repeated
does not quite accurately describe the situation - array elements are just overwritten when indices are encountered another time(s), and awk does this as any other programming language.

DEBCONF-MERGETEMPLATE(1)					      Debconf						  DEBCONF-MERGETEMPLATE(1)

NAME
debconf-mergetemplate - merge together multiple debconf template files SYNOPSIS
debconf-mergetemplate [options] [templates.ll ...] templates DESCRIPTION
Note: This utility is deprecated. You should switch to using po-debconf's po2debconf program. This program is useful if you have multiple debconf templates files which you want to merge together into one big file. All the specified files will be read in, merged, and output to standard output. This can be especially useful if you are dealing with translated template files. In this case, you might have your main template file, plus several other files provided by the translators. These files will have translated fields in them, and maybe the translators left in the english versions of the fields they translated, for their reference. So, you want to merge together all the translated templates files with your main templates file. Any fields that are unique to the translated files need to be added in to the correct templates, but any fields they have in common should be superseded by the fields in the main file (which might be more up-to-date). This program handles that case properly, just list each of the translated templates files, and then your main templates file last. OPTIONS
--outdated Merge in even outdated translations. The default is to drop them with a warning message. --drop-old-templates If a translation has an entire template that is not in the master file (and thus is probably an old template), drop that entire template. SEE ALSO
