 From:
 https://gis.stackexchange.com/questions/258089/v-clean-with-rmarea-and-
 lat-long-projection

 There is some confusion concerning this message:
 main.c:
 {{{
     /* TODO: threshold might be recalculated with optional geodesic
 support to meters */
     if (G_projection() == PROJECTION_LL)
         G_important_message(_("Note: In latitude-longitude coordinate
 system specify threshold in degree unit"));
 }}}

 while the documentation reads:
 {{{
 grep meter v.clean.html
 case, also the threshold parameter requires several values to be listed
 Threshold must always be in square meters, also for latitude-longitude
 locations or locations with units other than meters.
 }}}

 Should the G_important_message() be removed from main.c?
