The charge ordering observed in the (TMTTF)$_{2}$X family has been studied by X-ray absorption spectroscopy. XANES measurements at the Sulfur K-edge show no evidence of charge disproportionation larger than 0.5 e, and EXAFS at the Phosphorus K-edge indicate no displacements of the PF$_{6}$ anion larger than 0.05 Å. The difficulty to observe a structural signature of this charge ordering is due to the triclinic symmetry of these salts. By contrast, in the monoclinic charge transfer salt (DMtTTF)$_{2}$ClO$_{4}$, a screw axis symmetry constrains the molecular stacks to be uniform. In this real $\scriptstyle 1/4$-filled system, charge localization is observed at about 150 K. We show that around this temperature an incommensurate modul...
