You just answered it, so I guess you found it. ;-)

Right.  That will concatenate them and result in the string "barbaz".

Can you change that to:

ti->name = grub_strdup (args[0]);

(So only one space before `=')

Another thing you could do is not malloc'ing memory, but using a
pointer to a pre-defined struct instead.  When free'ing you need a
special case to check if it is this pre-defined struct.
