[spp] [PATCH 10/11] docs: refactor for character length

[ogawa.yasufumi@lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>

For documentation, lines should be less than 80 characters and expecially
must be in literals blocks. This patch is for revising for the rule.

Signed-off-by: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>
