(maint) Fix location_for helper method

Without this patch the location_for helper method in the Gemfile
incorrectly assumes the mdata variable has a value.  This patch
addresses the problem by explicitly binding the regular expression match
results to the mdata variable to ensure it has a value when accessed by
index.
