Use vim to edit a file leads to create two files that aren't cleaned.

Example after editing qt-for-ivi-shell file :

rw-rr-. 1 root root  601 Nov  7 09:23 .qt-for-ivi-shell.un~
rw-rr-. 1 root root   39 Nov  7 09:23 qt-for-ivi-shell
rw-rr-. 1 root root   40 Nov  7 09:23 qt-for-ivi-shell~

This is a big problem when those left working files are processed by applications, like application framework.
