Wrap some PETSc documentation lines.

These are quite long and missing some HTML.

-   *   <li> Local solvers: Solvers for each subdomain. These are performed concurrently by each processor
-   *   <li> A coarse solver: Continuity between each subdomain is imposed in a small number of DoFs, referred to as <em>primal DoFs</em>. This solver solves such problem.
