Changes to allow path to the isle-dc repo to have spaces

[ysuarez]

This pull request is an attempt to fix issue #235 to allow the path to the isle-dc repo to have spaces without causing errors when using makefile commands.

Regretfully there are still issues with this pull request in the drupal-public-files-import target from its use of the SRC makefile variable.

To test this run make demo

I put the details on the errors I am still getting and what I think are the reasons in issue #235

[DonRichards]

The quickest solution is a warning (I just added it). I've tried a few basic methods for escaping the character [space] but have been unsuccessful. It's likely to only take a bit more time but that's additional time than I currently can't invest.

[DonRichards]

@ysuarez Do think that will be good enough for now?

[ysuarez]

@DonRichards Yes, I think that warning is good enough for now.

If and when when you have time, can you put in here or tell me by Slack what methods you tried that failed so far, so I (or someone else) can use that data to help figure out other ways to try fix the remaining path issues.

[ysuarez]

@DonRichards I just tested your changes and the error message was triggered and makes sense.

make demo
Makefile:11: *** Containing path cannot contain space characters: '/path/with/a space/isle-dc'.  Stop.

I would support merging this PR , though I am not an ISLE2 developer and "take it with a grain of salt," or at the very least I would suggest that we just add the part that checks if there are spaces in the path.

I believe this is limitation with Make per this really old bug report http://savannah.gnu.org/bugs/?712

Works for me.
