[GRASS5] [bug #2879] (grass) imagery.html cleanup

this bug's URL: http://intevation.de/rt/webrt?serial_num=2879
-------------------------------------------------------------------------

imagery.html:
# i.gensig - Generates statistics for i.maxlik from raster map layer.
# i.gensigset - Generate statistics for i.smap from raster map layer.
# i.group - An imagery function that creates and edits groups and subgroups of imagery files. The interactive version provides extended functionality.

No need to say "An imagery function that" in the last one.

Another:

# i.smap - An imagery function that performs contextual image classification using sequential maximum a posteriori (SMAP) estimation.

Indeed, you could regularize each sentence so none stick out.
Here some have their names repeated:

# i.spectral - i.spectral - displays spectral response at user specifified locations in images
# i.target - This program targets an imagery group to a GRASS location and mapset
and that one says 'this program'.

Also do check vector.html, etc.
