Yes that part is fixed.

I have been working on merging the cmsis-dap support and also ran into this
problem as well.
See http://repo.or.cz/w/openocd/ntfreak.git/shortlog/refs/heads/cmsis-dap
and in particular the changes I am thinking about in
http://repo.or.cz/w/openocd/ntfreak.git/blob/7788d9faa1c3970b0cac5eec34fbed6b1df07753:/tcl/target/swj-dp.tcl
A cfg that uses this change is
http://repo.or.cz/w/openocd/ntfreak.git/blob/7788d9faa1c3970b0cac5eec34fbed6b1df07753:/tcl/target/stm32f1x.cfg
Not sure if using the jtag_mode var is the best method but it may be a
start.
