Change subject: vty_transcript_test.vty: add choice auto-complete tests
......................................................................


Patch Set 1:

The problem is somewhere in cmd_execute_command_real(). Instead of composing 'argv' from 'vline', we need to use 'matched_element'.

Some info from gdb:

  $ gdb -q ./vty_transcript_test
  (gdb)$ b command.c:2322

  $ telnet localhost 42042
  $ vty_transcript_test> th

  (gdb)$ bt
