This patch fixes this problem, and now it appears to work (not that I
have tested it extensively!)
The problem was that, when resume issued the software single step
command, it cleared `step'. Later on, it would test whether step was
zero and think it had been asked to `continue'. Ok to install?

* infrun.c (resume): Do not change continue to step if we single
step on software.
