ACK with nits fixed. Still to go - it would be nice to follow up with a
4/3 that converts virsh.c cmdEcho to use virBufferEscapeShell.

You are guaranteed that quoted is not NULL, by virtue of the fact that
you already filtered for virBufferError just beforehand. Drop this if
statement.

Rebase this on top of my comments for 1/3 (no long lines). Also, add
one more test where $NC is something that actually proves things work
with shell meta-characters, perhaps by passing 'nc -4' as the value that
eventually supplies the %s for $NC, so that .expectOut will include: sh
-c 'if ''nc -4'' -q 2>&1 ....
