Subject: play: Fix off-by-one in jmp 100.
X-Git-Tag: v0.5.6~61^2~1
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=73f00df1d8dea3793c9f436b9348074bc6f9aaba;p=paraslash.git

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".
