Internal call gdal_translate from grdcut, source grid filename with spaces not working

Hi, source grid filename with spaces not working when calling grdcut on a geotiff. The internal gdal_translate receives filename not quoted so spaces in the file name cause an error. Extract from the debug output below.

Calling gdal_translate instead directly with filenames surrounded by quotes works.
Problematic filename in my case is:
"Canadian Hydrographic Service NONNA bathymetry/NONNAP_9_TIFF/TIFF/NONNAP10_4400N06400W.tiff"

I think this may be a bug in filename handling.

Relevant debug output from grdcut:

Thanks, we occasionally find these issues. We developers grew up in a time when using spaces in file names or directories was considered the equivalent of purposefully stabbing oneself in the foot.
At any rate, I will submit a PR to fix this issue - the use of gdal_translate from grdcut is relatively new and hence not tested on such filenames!

If you are able to build from git source then please try out this pull request that I hope fixes the problem.

Now approved and merged into the master branch.

Thanks! Sorry for silence, was too busy to follow. Anyway I am not qualified enough to build from git sources within a reasonable time.
