to me.

I think awk is the way to go:

awk '/^#/ {comment[c++] = $0}
     /^# FAKVORTO: MATEMATIKA/ {verify = 1}
     /^msgid/ {msgid = $0}
     /^msgstr/ {if (verify == 1) {
                  for (l=0; l<c; l++)
                    print comment[l]
                  print msgid
                  print
                  }
                c = 0
                verify = 0}'
