 > If I remember correctly, the reason to remove it was that there was too
 many ways how to start GRASS GIS (with cmd.exe, with MSYS, and than
 without GUI guess). The other reason was too different behaviors on
 Windows (in cmd.exe and in MSYS) and finally also problems with MSYS
 itself mostly the encoding (would have to find the emails to confirm
 those).

 e.g. windows command console understands slash and backslash in paths, see

 {{{
 D:\wd\sample_data>cd D:\wd\sample_data\otherdata

 D:\wd\sample_data\otherdata>cd ..

 D:\wd\sample_data>cd D:/wd/sample_data/otherdata

 D:\wd\sample_data\otherdata>
 }}}

 not sure if MSYS handles all these cases of path issues.

 in the OSGeo4W shell based on the windows native command line, you can
 still start GRASS without GUI, e.g.

 {{{
 D:\wd\sample_data\otherdata>grass74 --text

 locale setting'

 also

 {{{
 grass74 --exec MyScript.bat D:/myGrassData/MyLoc/MyMapset
 }}}

 works on the OSGeo4W shell; anyone tested if this works with MSYS?

 also GRASS-R-integration works in the windows command line:

 {{{

 anyone tested if this works also with MSYS?

 and I also remember encoding issues.
