Directory path in packages file gets ignored

[dhoer]

So requirements.txt with line colorbrewer -d /matlab:

export_fig -u http://www.mathworks.com/matlabcentral/fileexchange/23629-export-fig 
matlab2tikz -t 1.0.0
colorbrewer -d /matlab

Would get rewritten as mpm install colorbrewer -d /matlab -d /home/matlab/mpm/mpm-packages -c default:

>> mpm install -i requirements.txt
Using collection "default"
About to run the following commands: 
   mpm install export_fig -u http://www.mathworks.com/matlabcentral/fileexchange/23629-export-fig -d /home/matlab/mpm/mpm-packages -c default
   mpm install matlab2tikz -t 1.0.0 -d /home/matlab/mpm/mpm-packages -c default
   mpm install colorbrewer -d /matlab -d /home/matlab/mpm/mpm-packages -c default
Confirm (y/n)? 

Ignoring the path of /matlab/colorbrewer:

Updating paths...
   Adding to path: /home/matlab/mpm/mpm-packages/colorbrewer

Yeah good find! Should be straightforward to fix. I'll just need to add some extra cases to readRequirementsFile(), to ensure that if -d is provided (or -c as well) inside requirements.txt, you cannot say something like mpm install -i requirements.txt -d example.
