Tag Alias: long_coat -> overcoat

Should the long_coat tag be aliased to the overcoat tag?There are wiki pages for both,although overcoat seems to be the correct term.

Would aliases for 'longcoat' and 'over_coat' be necessary as well?More for prevention than anything,since nobody created such a tag as yet.

Unless someone can provide a distinct definition for long_coat that separates it from overcoat, I'll alias to overcoat.
