Extra spaces on command line interpreted as part of file name

[gardrek]

When a command expects a file or directory name, any extra spaces around it are interpreted as part of the name. I am not sure if this is a bug or a feature, as there seems to be no other way to address names starting or ending with a space.

For instance, when using the load command with a cart file name, an extra space before or after the name causes it to fail with cart loading error.
