Fails if the path to the package contains a `(`

[orgadish]

The path to my package contains a (. When I run changer I get the following error (anonymized):

sh: -c: line 0: syntax error near unexpected token `('
sh: -c: line 0: `'mv' /Users/orgadish/Dropbox (Work)/R packages/my_package /Users/orgadish/Dropbox (Work)/R packages/my_new_package'

What I've done so far is to move it to a different folder, run changer and then move it back.
