The words and cword variables are not localized in all Bash completion scripts that call _init_completion. cur, prev, words, and cword (and split if using the -s flag) are all variables that should be localized in Bash completion scripts before calling _init_completion (even if they don't otherwise appear in the calling script). This is done for cur and prev, but not for words and cword. Letting words and cword remain unlocalized may clobber variables the user is using for other purposes, which is bad. This issue can be resolved by declaring words and cword as local variables. Resolves #19188.
