Bugs-everywhere (BE) is kind of neat idea - keep the bugs in your repo.
On MS Windows to get the editor to work for BE comments you need to add a Windows path to an editor since it calls Python's os.system, and not a shell command. If you are using msysgit this can conflict with git since it will read $EDITOR and execute it as a shell command.
To circumvent this, add $GIT_EDITOR which is read by git before $EDITOR. See git-var.
This is easily done if you've set up BE in a virtualenv and especially easy if you have virtualenvwrapper. Either way add to the script file.
postactivate/activate for virtualenvwrapper/virtualenv
# reset git var to vi, GIT_EDITOR is read before EDITORpredeactivate/deactivate for virtualenvwrapper/virtualenv
# set bugs-everywhere EDITOR to vim
# must use windows path since it calls os.system
# remove bugs-everywhere EDITOR
# remove git var GIT_EDITOR
note that you need double quotes around the Windows path because it get's expanded twice.
