I like the idea of a new switch on /hadd /hdel /hinc /hdel to indicate the item name is quoted.
The fact that mIRC doesn't load the last line with odd numbered line number should be a seperate report imo, it has nothing to do with quoted item name, if you make this same switch 'fix' the way mIRC handle this last line situation, it's then not possible to get that behavior only as well with the current hash table behaviors.
