Well I am looking at the Grass prompt, and it displays the current _mapset_, 
but not the current _search path_. The quickest way of displaying the search 
path is to define an alias for a new 'g.mapsets' command, and put it somewhere
appropriate like $GISRC.cshrc, eg: 

set prompt = "GRASS 4.2 > "
alias g.maps '$GISBASE/bin/g.mapsets mapset=\!*; echo "Mapset <${MAPSET}> in Location <${LOCATION_NAME}> with Search-Path <\!*>"'

Usage: g.maps mapset1[,mapset2...]

The slower solution is of course to hack the g.mapsets code.
