Subject: [PATCH] Proposition : enhancement of tag sub/sup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Proposition helps to avoid bad line-height rendering caused by sub and sup tags. (use these tags on big blocks of texts with and without the fix to see the difference)

In french : la proposition aide à éviter des interlignages disgracieux causés par les balises sup et sub. ;)
