For anyone attempting to follow the previous instructions for modifying the subplot function, it is also necessary to reset the variable def_pos to [0,0,1,1] after about line 237 (and comment out the code setting it if you care about efficiency).

This is the reason I haven't used subplot for quite a while. I wrote my own function tight_subplot for easy control on the space between and around the plots.
Bringing up this topic motivated me to finally write a short help section and submit it to the FEX. "quick hack for my own use" but it could be useful for somebody anyway.
