Description

dsync, and probably dcp, are handling source/destination arguments incorrectly.
Example:
source /a/b where b is a directory (with say /a/b/f being a file)
destination /c/.
dsync /a/b /c/.
results in the contents of /a/b being copied to /c resulting in /c/f, where as the correct behavior is that b is copied to c, with /c/b being the result.

I.e. dsync/dcp should adhere to how rsync/cp behaves.

Research direction

Start by locating the source/destination argument handling for dsync and dcp, then reproduce the /a/b to /c/. example from the issue. Compare the resulting paths with rsync or cp behavior; done means the directory is placed at /c/b rather than copying only its contents into /c.
