This is a good idea but it may not be necessary.   If you poke around
in src/tla/=TODO you can see that the idea there is to add a directive
to =tagging-method, `embedded-tag REGEXP'  as in:

        tagline == 
                external-tag
                embedded-tag            ^[[:punc:]]*arch-tag:[[:blank:]]*
                untagged-source         source

Part of the implication of the recent discussions is that, in addition
to a regexp just to find the id line, we will need a regexp to find
the part of that line that contains the tag, and a value to say how 
the tag is quoted:


        tagline == 
                external-tag
                embedded-tag,line=>     ^[[:punc:]]*arch-tag:[[:blank:]]*
                embedded-tag,cstr=1     
^[[:punc:]]*arch-id:[[:blank:]]*("([^\"]|\\.)")
                untagged-source         source

Soon we'll be write up there with sendmail.
