#2 Allow scp2dos to use file globbing

[Jeff Evans]

Unfortunately, on all the servers I tried scp would only copy one file at a time when globbing.
Upon closer inspection I found that scpdos.c was not expecting the filenames to be null delimited.
See the attached patch (hack :-) which fixes the issue. Additionally, using [.,.] and {.,.} expansions should also now work.
