Those don't take up any space in the actual compiled opcodes.  The only
space you could save is in the string that the file is initially loaded
into and the $eval string that gets built up to pass to eval().

I'd just like to add an example which shows you what exactly perl sees when it 
compiles your code:

perl -MO=Deparse -le '\
print \
"this is a string" \
# hmm, some comment \
. "another string" \
# bummer, i should end the line now \
;'
prints:

BEGIN { $/ = "\n"; $\ = "\n"; }
print 'this is a stringanother string';
-e syntax OK
