| Description | Composr tries to limit RAM used by tabular catalogues by flattening the Tempcode tree for each table row. However the Tempcode engine still can use a lot of memory when large numbers of flattened rows are appended. PHP generally is a real memory hog due to the way it stores loosely-typed dynamic data structures.
Refactor the Tempcode engine so that concatenated flattened segments are done as a single string sequence by detecting the intention for optimisation and being clever about manipulating how things are concatenated. |

The Tempcode optimisation made in #526 doesn't always work. Fix failure case.
