For command line options which permit '?' meaning 'please list the permitted values', add support for 'help' as a synonym, by abstracting the check out into a helper function. Update the documentation to use 'help' rather than '?', since '?' is a shell metacharacter and thus prone to fail confusingly if there is a single character filename in the current working directory and the '?' has not been escaped. It's therefore better to steer users towards 'help', though '?' is retained for backwards compatibility. We do not, however, update the output of the system emulator's -help (or any documentation autogenerated from the qemu-options.hx which is the source of the -help text) because libvirt parses our -help output and will break. At a later date when QEMU provides a better interface so libvirt can avoid having to do this, we can update the -help text too. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> --- Since we've agreed not to change the -help output for QEMU 1.2 this is basically just the v1 patch with the qemu-options.hx changes dropped. bsd-user change still only eyeballed, not compiled. arch_init.c | 4 ++-- blockdev.c | 10 +++++----- bsd-user/main.c | 6 +++--- hw/mips_jazz.c | 2 +- hw/qdev-monitor.c | 2 +- hw/watchdog.c | 2 +- linux-user/main.c | 4 ++-- net.c | 3 ++- qemu-common.h | 16 ++++++++++++++++ qemu-doc.texi | 2 +- qemu-ga.c | 2 +- qemu-img.c | 4 ++-- qemu-timer.c | 2 +- vl.c | 4 ++-- 14 files changed, 40 insertions(+), 23 deletions(-)
