luaK_concat concatenates two lists of pending jumps. So, the call

will create a new jump instruction (luaK_jump) and add it to the
'escapelist'. The luaK_patchtohere function patches all jump
instructions in the given list to jump to the current instruction
("here"). So, the call
> luaK_patchtohere(fs, escapelist);
in the end of the ifstat will make all jumps in the 'escapelist' to
jump to the end of the statement.
