Personally I would prefer an option to the cygwin.bat like -rxvt. Otherwise
I had to duplicate my settings in both files. Additionally I would not
replace the link in the start menu, but add another one.

What I do not like with the current batch file approach is, that it does
only support global settings, not personal ones (nor does it respect my
favorite choice of the shell from /etc/passwd). This is not an issue, if I
am the only  person using the machine.
