c:\ToPs_DevTools\CygWin\bin\grep.exe --colour=auto -n "^[^() ]*M_Auswahl[^() 
]*$" *.a26




Same call with version 2.5.1


c:\ToPs_DevTools\CygWin.org-2009\bin\grep.exe --ver
grep (GNU grep) 2.5.1

c:\ToPs_DevTools\CygWin.org-2009\bin\grep.exe --color=auto -n "^[^() 
]*M_Auswahl[^() ]*$" *.a26
cad_base.a26:11150:M_Auswahl


Version 2.5.4 use  black forground color on black background color if i use 
-color=auto
Running in cmd.exe on Win7 64Bit
