It is a bad idea to call gettext on an already-translated string. In cases where a string must be translated separately from where it is exposed to xgettext, the gettext manual recommends the idiom of N_() wrapping gettext_noop for marking the string. * src/internal.h (N_): Fix definition to match gettext manual. * tools/virsh.c: (cmdHelp, cmdList, cmdDomstate, cmdDominfo) (cmdVcpuinfo, vshUsage): Replace incorrect use of N_ with _. (vshCmddefHelp): Likewise. Mark C format strings appropriately.
