pscp -scp: fix spurious newlines at end of filenames.

Browse Source 
Commit d07d7d66f introduced this bug: I replaced a manually grown
string buffer with a strbuf, and failed to replicate the part where
after I'd finished appending wire data to the string I removed the
terminating \n. That string was used as the local file name, when
downloading in SCP mode using a wildcard, so you'd get lots of local
files whose names ended inconveniently in a newline character.

Fixed by terminating the loop before we push the \n on to the strbuf
in the first place.
