That won't work in general, because there are other kinds of markup
that end up indented like @example.

And even @example is not always indented exactly 5 spaces, because the
surrounding markup can affect that.  E.g., look at the code fragment
around line 127 of the "Time Conversion" node in the ELisp manual.

We cannot build a feature on such shaky foundations.  When 'makeinfo'
produces the Info output, the markup information is all but lost, and
nothing can bring it back.
