[Bug-wget] WGET bug with --timestamping

[Jay Pellam]

Confirmed in 1.10.1, the latest binary Windows build I've found.
Was also in 1.8.2, the previous Win32 version I have.

Contrary to what the help says (--timestamping: don't re-retrieve files unless 
newer than local), WGET re-retrieves the file and overwrites a NEWER file if 
the sizes are different.

        The sizes do not match (local 45025) -- retrieving.

To me this seems clearly wrong.  There is no question that its wrong when the 
performance is compared to the documentation.  I could understand why you might 
not want to change this behavior absolutely but if not a new switch should be 
provided, eg, --ignoresize.

For the documented purpose (mirroring) it seems like it could be disasterous in 
many situations.
