The "while read" probably read the final line just fine, but it also hit the end of file since there was no newline at the end of it, thereby exiting the loop.

Code:
$ printf 'a\nb' > test1.txt
$ od -cb test1.txt 
0000000    a  \n   b                                                    
          141 012 142                                                    
0000003
$ while read line; do echo IN WHILE: $line; done < test1.txt ; echo AFTER WHILE: $line
IN WHILE: a
AFTER WHILE: b

You could try the following to ensure that the loop body executes if the final "line" isn't newline terminated:
Code:
$ while read line || [ "$line" ]; do echo $line; done < test1.txt
a
b

sftp-server(1M) 					  System Administration Commands					   sftp-server(1M)

NAME

       sftp-server - SFTP server subsystem

SYNOPSIS

       /usr/lib/ssh/sftp-server [-f log_facility] [-l log_level]

DESCRIPTION

       sftp-server implements the server side of the SSH File Transfer Protocol as defined in the IETF draft-ietf-secsh-filexfer.

       sftp-server  is a subsystem for sshd(1M) and must not be run directly. Command-line flags to sftp-server should be specified in the Subsys-
       tem declaration. See sshd_config(4) for more information.

       To enable the sftp-server subsystem for sshd add the following to /etc/ssh/sshd_config:

	 Subsystem   sftp     /usr/lib/ssh/sftp-server

       See sshd_config(4) for a description of the format and contents of that file.

       There is no relationship between the protocol used by sftp-server and the FTP protocol (RFC 959) provided by in.ftpd.

OPTIONS

       Valid options are listed below. As stated above, these are to be specified in the Subsystem declation of sshd_config.

       -f log_facility

	   Specifies the facility code that is used when logging messages from sftp-server. The possible values are: DAEMON, USER,  AUTH,  LOCAL0,
	   LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. The default is AUTH.

       -l log_level

	   Specifies  which  messages  will  be logged by sftp-server. The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1,
	   DEBUG2, and DEBUG3. INFO and VERBOSE log transactions that sftp-server performs on behalf of the client. DEBUG and DEBUG1  are  equiva-
	   lent. DEBUG2 and DEBUG3 each specify higher levels of debugging output. The default is ERROR.

EXIT STATUS

       The following exit values are returned:

       0     Successful completion.

       >0    An error occurred.

FILES

       /usr/lib/ssh/sftp-server    Server-side binary.
