You can probably guess why I am suggesting this. Doh!
Just two new lines in applications/admin/controllers/default.py under
the edit def try/except block:
try:
olddata=data # GRAB OLD DATA
data=request.vars.data.replace('\r\n','\n').strip()+'\n'
open(apath(filename + '.bak'),'w').write(olddata) # SAVE TO BAK
FILE
open(apath(filename),'w').write(data)
response.flash=T("file saved on %(time)s",dict(time=time.ctime()))
except Exception: pass
You could even get fancy an add a Restore button.
