Something equivalent to:

  cat /var/lib/dpkg/available |
    awk '/^Package:/ {P=$2;V=""}
         /^Version:/ {if (V=="") { V=$2; } }
         /^Source: .* (.*)/ {V=substr($3,2,length($3)-2)}
         /^Source:/ {P=$2}
         /^$/ { print "Source-Package:", P; print "Source-Version:", V }
         {print}'

I would've thought. (That adds "Source-Package:" and "Source-Version:" 
fields to every stanza)

The idea being that "grep-available --source-info [...]" would work the 
same as piping the above into "| grep-ctrl [...]".
