No. curl will not modify your local file according to the contents of what
you download. curl downloads the data you ask for, you do the fiddling you
need.

You can _easily_ get this feature by using a curl binding for your favourite
script language, use libcurl and write your own tool that does this or even
edit the curl source code to make it do this.

I don't think this is a feature that many people are looking for and you
won't catch *me* implementing this for a very long time! ;-)

Good luck!
