play: Fix off-by-one in jmp 100.

The command "jmp 100" did not work as expected (switch to the next
file) but caused the following error

	repos failed: Invalid argument

The problem was that ->start_chunk was set to pt->num_chunks which
exceeds the maximal valid chunk number by one.

This commit special cases the value 100 to make "jmp 100" equivalent to
"next".
