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

[Jim Meyering]

* 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.
