A displaylines with an eqdef: text mre more more more more more more
more more more more more more more more more more text.
$$\displaylines{x=1 \eqdef{eqdef-displ}\cr}$$

{\leftskip = 14pt

And a indented normal equation:
$$y=2\eqdef{foo}
$$
An indented displaylines with an eqdef:
$$\displaylines{x=1 \eqdef{eqdef-displ}\cr}
$$

Now the same two with hangindent nonzero.
\hangindent=17pt 
And a indented normal equation:
$$y=2\eqdef{foo}
$$
An indented displaylines with an eqdef:
$$\displaylines{x=1 \eqdef{eqdef-displ}\cr}
$$

Well?
