Now, instead of always passing the optname, "domain", to vshCommandOptDomainBy, that function requires that its command argument refer to an opts array containing a "domain" option.

remove redundant optname arguments This is the second part of the change mentioned here: http://thread.gmane.org/gmane.comp.emulators.libvirt/10331 It removes the essentially redundant "optname" parameter from each of the vshCommandOptNetworkBy and vshCommandOptDomainBy functions as well as the correspond macros (without "By" suffix). Now, instead of always passing the optname, "domain", to vshCommandOptDomainBy, that function requires that its command argument refer to an opts array containing a "domain" option. This normalization makes one more help-related change: it renames the net-start "name" argument to the more sensible and consistent "network". * src/virsh.c (VSH_BYNAME, vshCommandOptDomain) (cmd_has_option): New function, used in vshCommandOptDomainBy and vshCommandOptNetworkBy. (vshCommandOptDomainBy, vshCommandOptNetworkBy): Remove the optname parameter, it's always "domain" ("network"). Update all callers. Call cmd_has_option. (vshCommandOptNetwork, cmdAutostart, cmdConsole, cmdDomstate) (cmdDomblkstat, cmdDomIfstat, cmdSuspend, cmdUndefine, cmdStart) (cmdSave, cmdSchedinfo, cmdDump, cmdResume, cmdShutdown) (cmdReboot, cmdDestroy, cmdDominfo, cmdVcpuinfo, cmdVcpupin) (cmdSetvcpus, cmdSetmem, cmdSetmaxmem, cmdDumpXML, cmdDomname) (cmdDomid, cmdDomuuid, cmdMigrate, cmdNetworkAutostart) (cmdNetworkDestroy, cmdNetworkDumpXML, cmdNetworkName) (opts_network_start, cmdNetworkStart, cmdNetworkUndefine) (cmdNetworkUuid, cmdVNCDisplay, cmdTTYConsole, cmdAttachDevice) (cmdDetachDevice, cmdAttachInterface, cmdDetachInterface) (cmdAttachDisk, cmdDetachDisk, cmdEdit) * src/Makefile.am (virsh-pool-edit.c): This code is generated from cmdEdit, and cmdEdit uses the vshCommandOptDomain macro which now, with the changes above, has only 3 (was 4) arguments, yet the macro use is mapped to vshCommandOptPool, which still requires 4 arguments. So this change adjusts the sed code to reinsert the just-removed argument -- we're not changing pool-related code right now, because it's not as straight-forward.
