When git-dude looks for git repositories, it will break on directories with spaces in the name.
To reproduce, clone a repository into git-dude's working folder. Change the name of the directory to include a space, for example, "my repo". Upon running git-dude, bash will give an error saying git-dude/git-dude: line 44: cd: my: No such file or directory.
git-dude/git-dude: line 44: cd: my: No such file or directory
This commit fixes the problem by wrapping the directory names in double quotes.
Fixed looking for dirs with spaces
