mark comment-{start,end}[-skip] as safe-local-variable

[Dan Nicolaescu]

/etc/termcap on my Fedora Core 5 system uses comment-start and
comment-start-skip, so given that they are actively used as local
variables, they should be marked as safe. 
By analogy *-end variables should be also be marked as safe.

Should I check this in?
