We need to capture
refkey and move it from the
:PROPERTIES: block to beginning of header.
Note: Pre-ARC standard was using label «cite-key». ARC uses
refkey as more correct, while leaving the former name to bibliography use.
This regex captures
- base-ref as $1
- unit-ref as $2
- possible editorial flag as $3
