Include a comment or play on spaces. Sample:
90 0 obj <<
/Contents 95 0 R
/Resources 94 0 R
/MediaBox [0 0 595.276 841.89]
/Parent 122 0 R
/Annots [ 104 0 R 108 0 R 109 0 R 110 0 R ]
This is one object taken from one of my pdfTeX documents.
If I need a few chars, I could delete as many spaces as necessary (or
newlines) as the PdF lexer allows me to. Shortest valid expression (if I
90 0 obj<</Type/Page/Contents 95 0 R/Resources 94 0
R/MediaBox[0 0 595.276 841.89]/Parent 122 0 R/Annots [104 0
R 108 0 R 109 0 R 110 0 R]>>endobj
I think I gained a dozen bytes.
