Lintian tag information: source-contains-editor-backup-file (type: warning)

Description (from lintian-explain-tags)

The Debian diff or native package contains a file ending in ~ or of the
form .xxx.swp, which is normally either an Emacs or vim backup file or a
backup file created by programs such as autoheader or debconf-updatepo.
This usually causes no harm, but it's messy and bloats the size of the
Debian diff to no useful purpose.
