[Bug-wget] Please review my patch for bug #29518

[Leonard Ehrenfried]

Hi,

I've been poking around the wget bug tracker and implemented the following
feature request: https://savannah.gnu.org/bugs/?29518

I have put up a repo at launchpad here:
http://bazaar.launchpad.net/~leonard-ehrenfried/wget/purge-input-file/changes

The way I have implemented is, that the input file is re-read into a linked
list after each successful download (status==RETROK) and the the URL that
has just been read is not written back to the input file. Is that an
appropriate way to go about this?

I'd be greatful for a ruthless code review - it's the only way to learn!

Thanks
Lenni

PS: I might need a better name for the command line option:
'purge-input-file' sounds a bit drastic.
