unace l is not listing full filenames

[Paulo Marcel Coelho Aragão]

'unace l' is not listing full filenames, and there's no documented option to make it do so. Here's the output for this ace archive (https://1drv.ms/u/s!AlsiEMDuBseItC-X2FDXqFBM2uNy):

This breaks mc's extfs uace, which depends on the full filenames to work. Current package unace (1.2b-15) shows full filenames but can't extract recent ace archives.

Running unace-nonfree 2.5-9 on Xubuntu 17.10

Let me know if I can help debug this further.
