 See what are the initial rights for the files that a given GRASS vector
 layer is composed of:

 {{{
 $ ls -lr dbf/pokrycie_przyborow_u65_10k.dbf
 vector/pokrycie_przyborow_u65_10k
 -rw-rw---- 1 ms      users-grass  466 2008-07-02 19:07
 dbf/pokrycie_przyborow_u65_10k.dbf

 vector/pokrycie_przyborow_u65_10k:

 }}}


 As can be seen both group and owner can edit data. Now I open the vector
 in QGIS GRASS Edit, modify a feture and quit. QGIS modifies file access
 rights for the group, preventing other group members from being able to
 edit the data from now on:

 {{{
 $ ls -lr vector/pokrycie_przyborow_u65_10k
 dbf/pokrycie_przyborow_u65_10k.dbf
 -rw-r--r-- 1 ms      users-grass  375 2008-07-02 19:14
 dbf/pokrycie_przyborow_u65_10k.dbf

 vector/pokrycie_przyborow_u65_10k:

 Please don't!
