- Avoids code-repetition especially so when support
  for more key types are added.

v2: Same as the ACK-ed v1 but the extra newline removed.

Your patch has been applied to the master branch.

(I took the ACK from Steffan for v1, and verified that v2 is really idential
except for the extra empty line - so line numbers differ, but code is the
same.  Adding an extra ACK from me for staring-at-the-code - trivial
enough in this case)
