Have you tried the debug minification? It's mentioned a bit below on the 'debug' heading, that 'debug' is a valid value for '--minify-level' (not mentioned at minify itself)

From the readme;
>> Note: Minification may interfere with the line number calculation, 
>> use --minify-level=debug to enable all features of minify that don't 
>> change line numbers, and everything will be fine.
