In SFTP, do not add '/' if homedir ends with one

[evigeant]

When using SFTP and a path relative to the user home, do not add a trailing '/' to the user home dir if it already ends with one.

Background:

We have an SFTP server which serves files out of a virtual directory structure. Because of this, the "HOME" directory for all users is "/" by configuration (we do not have user home directories in the virtual filesystem).

When using curl to upload files with a command such as this:
curl -T file_to_upload.txt sftp://hostname/~/folder/

curl first resolves the home directory to "/" and then uploads the file with this filename: //folder/file_to_upload.txt

In our case, this caused the path to be misinterpreted as a network path which ultimately caused the upload to fail. We will implement a fix in the SFTP server for this.

The fix here is simply such that curl uploads the file with this filename instead in this situation:
/folder/file_to_upload.txt

which is the intended path I believe.
