I'd drop hints below, but first...

... we would want an entry in .gitignore and Makefile as well ;-)

At this point, you would say:

	eval "
		GITHEAD_$w_tree='Stashed changes' &&
                GITHEAD_$c_tree='Updated upstream' &&
                GITHEAD_$b_tree='Version stash was based on'
	" &&
	export GITHEAD_$w_tree GITHEAD_$c_tree GITHEAD_$b_tree

I suspect you did not use eval and got syntax errors from variable assignment from the shell?

	VAR_$iable='Assign ment'

is a syntax error, while

	export VAR_$iable

is not.  Don't ask me why.
