Title: [rst-mode] Fixed strong, emphasis & literal rST

rST does not allow mixing strong with simple emphasis, further it
requires the stars to have a preceding and trailing whitespaces. Same
for literal text; e.g.

**strong** is correct, but **strong* is not, or
*emphasis* is correct, but *emphasis** is not.
