Assuming the new text is:
"By default only non-shared non-readonly images are transfered. Use
I<--migratedisks> to explicitly specify a list of disk targets to
transfer. B<disk-list> is a comma separated list then."
Change to:
"By default only non-shared non-readonly images are transferred. Use
I<--migratedisks> to explicitly specify a list of disk targets to
transfer via the comma separated B<disk-list> argument."
Note: transfered was misspelled... [I just searched on "comma " in the
existing document to find a few different examples...]
ACK (although existing still holds too!)
