[GRASS5] Inconsistencies among modules

[Rich Shepard]

  Two inconsistencies I've picked up:

  1)  Some modules (e.g., r.in.gdal, r.patch) allow the use of an existing
output file name with no warning that that file already exists, and asking
the user if it's OK to overwrite it. Other modules (e.g., r.poly, v.digit)
tell the user that the output file name exists, does not ask for directions,
and refuses to let the user overwrite it. Recommendation: always check,
always ask, follow the user's directions.

  2)  Most modules present a status indication of processing; usually the
percentage completed. Other modules (today it was r.poly) give no indication
whether they are slowly working or have silently passed away.
Recommendation: have a progress indicator for all modules.

Thanks,

Rich
