'gradle projects' could print project relative path

e.g. in the gradle project:

Root project 'gradle'
+--- Project ':announce'
+--- Project ':antlr'
+--- Project ':baseServices'
+--- Project ':baseServicesGroovy'
+--- Project ':buildComparison'
+--- Project ':buildInit'
+--- Project ':cli'
+--- Project ':codeQuality'
+--- Project ':core'
+--- Project ':coreImpl'
+--- Project ':cpp'
  ...

This structure does not reveal where the projects reside. In this case, they all reside in subprojects right now, but this could be more complex.
