added a quick alias for updating "update-request" files

tiny whitespace tweak (unrelated)
alias to turn on/off the Carp::Always thing in $PERL5OPT

I do this so often and I always have to look up the syntax, and the exact varname ... I'm tired of it
this mirrors the `msdebug` alias
it's not quite as good though:
-	it _could_ end up clobbering some completely unrelated use of $PERL5OPT
-	but I tried to make it as safe as possible
-	within the limits of tcsh shell programming <sigh>
-	besides: I never use $PERL5OPT for anything else, like, ever
