fix formatting issue

*Bond/react: Unknown section in map file*

   Please ensure reaction map files are properly formatted.

*Bond/react: Atom type affected by reaction too close to template edge*

*Bond/react: Bond type affected by reaction too close to template edge*

*Bond/react: Atom/Bond type affected by reaction too close to template edge*

   This means an atom which changes type or connectivity during the

   reaction is too close to an 'edge' atom defined in the map

   file.  This could cause incorrect assignment of bonds, angle, etc.
