Michal Privoznik 7657804df7 bash-completion: Fix argument passing to $1 ...

Our vsh bash completion string is merely just a wrapper over
virsh/virt-admin complete (cmdComplete) - a hidden command that
uses internal readline completion to generate list of candidates.
But this means that we have to pass some additional arguments to
the helper process: e.g. connection URI and R/O flag.

Candidates are printed on a separate line each (and can contain
space), which means that when bash is reading the helper's output
into an array, it needs to split items on '\n' char - hence the
IFS=$'\n' prefix on the line executing the helper. This was
introduced in b889594a70.

But this introduced a regression - those extra arguments we might
pass are stored in a string and previously were split on a space
character (because $IFS was kept untouched and by default
contains space). But now, after the fix that's no longer the case
and thus virsh/virt-admin sees ' -r -c URI' as one argument.

The solution is to take $IFS out of the picture by storing the
extra arguments in an array instead of string.
