If a problem occurs when update settings, the possibility which the user loses vim setting files exists.
The solution is needed...
An example of problems is "a user types Ctrl+C when update or switch".

vimsw/vimsw

Line 197 in 72e4cd8

if [ -f "$ORG_VIMRC" ]; then

If a user types Ctrl+C in Line 197, vim setting files disappear..

Signal Handling can be a solution??
Or do backup before delete vim setting files??
