* tests/virsh-synopsis: new file
* tests/Makefile.am (test_scripts): Add virsh-synopsis.
* src/virsh.c: Correct help SYNOPSIS for each of seven commands.

  ...
  invalid help SYNOPSIS for net-create:
      create a network from an XML <file>
  invalid help SYNOPSIS for net-define:
      define a network from an XML <file>
  invalid help SYNOPSIS for net-start:
      start <network>
  invalid help SYNOPSIS for pool-create:
      create a pool from an XML <file>
  invalid help SYNOPSIS for pool-define:
      define a pool from an XML <file>
  invalid help SYNOPSIS for pool-start:
      start <pool>
