Bug Report and patch fix

[kapil jain]

Hi,

I reviewed my previous patch which causes scp to exit if the file does not
exist rather than continuing the transfer if there are multiple input files.
Here is another patch which differs from previous one in functionality that
even if one file does not exist, continue with other input files and if
valid, continue to upload them rather then exiting the scp program if an
invalid file is found.
