Details:

The built-in editor seems to be malfuctioning. Precisely:
- pressing 'del' key resulted in deleting 7 chars
- the border of the edit menu screen on the right side looks broken (text goes
past the border)
- GRUB seems to discard the changes made in the editor and boots with the
previous options

Steps to reproduce:
- I boot to grub2
- I set the cursor on the desired line
- I press 'e' to enter edit mode
- I move down to the relevant line - in my case it is 'linux vmlinuz-old
root=/dev/sda5 ro'
- I set the cursor on the '-' between 'vmlinuz' and 'old'
- I press DEL
- 7 (!) chars are deleted
- I recreate the missing part of the line, which now looks like: 'linux
vmlinuz root=/dev/sda5 ro'
- I press F10 (or Ctrl-X, result is the same) to boot
- booted kernel is still vmlinuz-old (!)

I am using sys-boot/grub-2.00_beta2-r1 in Gentoo, which is based on svn trunk
version of GRUB.
