Re: [libvirt] [PATCH] fix just-broken "virsh start" and "virsh pool-start" commands

* src/virsh.c (cmdPoolStart, cmdStart): Change hard-coded vshCommandOptDomainBy string argument to match just-changed option name. Cole Robinson reported that "virsh start" was broken and provided that part of the fix. Bug introduced by yesterday's "virsh.c: tweak options to produce more accurate help". * tests/start: New file. Test for the above fix. * tests/Makefile.am (test_scripts): Add start. --- Without this change, "virsh start" and "virsh pool-start" would always fail. I'm fixing this in two steps: first is this patch: make the tiny string-changing fixes (along with the new test). Second will be a more invasive change to make it so the duplicate strings are removed altogether, so they'll never get out of sync again.
