Summary: Incorrect exit codes with multiple file transfer

Initial Comment:
Hi there,

I have noticed this bug since I started using cURL (7.19.6), but only reporting it now.
I am using the latest version 7.25.0 now, and the bug still persists.

In some cases when a failure occurs when sending multiple files with cURL an incorrect exit code "0" is given. Please see my tests below:

$ uname -a
SunOS V240-rd-2 5.10 Generic_147440-12 sun4u sparc SUNW,Sun-Fire-V240

$ curl --version
curl 7.25.0 (sparc-sun-solaris2.10) libcurl/7.25.0 OpenSSL/1.0.1 zlib/1.2.6 libidn/1.24 libssh2/1.4.1
Protocols: dict file ftp ftps gopher http https imap imaps pop3 pop3s rtsp scp sftp smtp smtps telnet tftp
Features: IDN IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP

TEST 1: All files transferred successfully - correct exit code:

$ curl --connect-timeout 10 --retry 8 --ftp-port - -# -T {file1,file10,file11,file12,file13,file2,file3,file4,file5,file6,file7,file8,file9} -u athed:Helpme12 ftp://172.21.2.232/

TEST 2: Now first half of files transferred successfully - correct exit code:

$ curl --connect-timeout 10 --retry 8 --ftp-port - -# -T {file1,file10,file11,file12,file13,file2,file3,file4,file5,file6,file7,file8,file9} -u athed:Helpme12 ftp://172.21.2.232/

TEST 3: Now a connection drop occurs in the middle of the transfer, 1 file was not successfully transferred, but an incorrect exit code 0 was given:
$ curl --connect-timeout 10 --retry 8 --ftp-port - -# -T {file1,file10,file11,file12,file13,file2,file3,file4,file5,file6,file7,file8,file9} -u athed:Helpme12 ftp://172.21.2.232/

TEST 4: Now there is a connection drop in beginning of transfer, and connection has gone up after first few files failed, but has given an incorrect exit code of 0:
$ curl --connect-timeout 1 --retry 1 --ftp-port - -# -T {file1,file10,file11,file12,file13,file2,file3,file4,file5,file6,file7,file8,file9} -u athed:Helpme12 ftp://172.21.2.232/

Is it possible to fix this bug? cURL to give correct exit codes for the failures above?

Thanks,
