Patch for better size handling of GRUB edit or shell

[Dr. Tilmann Bubeck]

Hi

especially on low resolution systems (e.g. VirtualBox with 800x600) the 
GRUB edit window (gfxmenu/view.c) and GRUB shell are hard to use, 
because they only use 70% of the available width, which is 800px * 70% = 
560px. Using the borders around the view makes the window even smaller. 
Please find attached a screenshot ("grub-unchanged-640x480-editor.png") 
showing the unmodified GRUB running in gfxmode=auto which is 800x600. 
You can see, that the edit window is ridiculus small.

Please find attached a patch, which changes the way, the view size is 
constructed. Before the patch it always used 70% of the available width. 
The patch checks if a full line of characters is fitting in these 70% 
and otherwise uses the available screen width, if it is not enough.

You can see the result in the second screenshot 
("grub-640x480-editor.png") attached. There is now much more room for 
the editor, without loosing the 70% style if enough space is available.

Could you please apply that patch or give any feedback?

Thanks!

 Tilmann Bubeck
