I don't understand this part of a sentence

This is the part that I don't understand:
only asking the advantages authors have in a second edition to correct some,faults of the first.

The Whole Passage goes like this:
That felicity, when I reflected on it, has induced me sometimes to say, that were it offered
to my choice, I should have no objection to a repetition of the same life from its
beginning, only asking the advantages authors have in a second edition to correct some
faults of the first. So I might, besides correcting the faults, change some sinister accidents
and events of it for others more favourable. But though this were denied, I should still
accept the offer. Since such a repetition is not to be expected, the next thing most like
living one’s life over again seems to be a recollection of that life, and to make that
recollection as durable as possible by putting it down in writing.

Please help me out in understanding it.
