[Cluster-devel] gfs2_edit: Fix signal handling and window resize

[Bob Peterson]

----- Original Message -----
| 
| This started out as a patch to remove the signal() call from this
| bit of code, but when I started looking in more detail, I
| spotted several other things which were wrong, so I fixed
| those instead.
| 
| Firstly ncurses has its own SIGWINCH handler these days, so
| we should not be overriding it, but instead, getting the info
| about resize at getch() time.
| 
| Secondly, the function for erasing the screen was using the
| supposed number of columns to index an array which was only 256
| in length, so although unlikely to happen in real life, this
| could cause an out of bounds access.
| 
| The simple solution seems to be to use ncurses own functions.
| I noted some comments about them not working correctly, but
| with the additional setting of the background attributes,
| that seemed to work ok to me, unless I'm missing something.
| 
| I've played around resizing the window and the like and it
| all seems to still be working correctly.
