When doing a get or put of a quoted filename, sftp misinterprets the location of the terminating 
quote. In sftp-int.c, when the terminating quote is located, the path is NUL terminated, but the 
location counter is not updated, causing the source filename's end quote to be interpreted as the 
opening quote of a destination filename. This causes 'get "filename"' to fail with an Unterminated 
quote error, and causes 'get "src-filename" "dest-filename"' to write src-filename to a file named " 
" rather than dest-filename. Unquoted transfer commands--e.g., get src-filename dest-filename--
are not affected.
