   - \ref DUMPATOMS : PRECISION option to set number of digits in output file.
   - \ref GROUP : NDX_FILE and NDX_GROUP options to import atom lists from ndx (gromacs) files.
   - In many multicolvars, MIN and MAX options can be used.
-  - \ref HISTOGRAM: GRID_SPACING (alternative to GRID_BIN to set grid spacing),
+  - \ref HISTOGRAM : GRID_SPACING (alternative to GRID_BIN to set grid spacing),
     FREQUENCY and FREE-ENERGY flags in addition to standard probability density,
     additional option for KERNEL=NONE to accumulate standard histograms. 
-  - \ref sum_hills: added options --spacing (alternative to --bin to set grid spacing)
+  - \ref sum_hills : added options --spacing (alternative to --bin to set grid spacing)
     and --setmintozero to translate the minimum of the output files to zero.
 - New features in MD patches (require repatch):
   - Gromacs 4.6.5 support \ref COMMITTOR analysis.
