Well, isn't that supposed to be done on the frontend side?

For instance, when a ADD transaction preparation fails, the frontend 
displays more details based on the pm_errno value returned by the 
library (as implemented in pacman_add function).

Could the same thing also be done for the sync part in 
alpm_trans_prepare() error handling code block, or did I miss the point?
