Rustdoc should only end the 1st sentence at a `.` that is followed by a space.

[orenbenkiki]

For example, if the 1st sentence is "This is the foo library version 1.0 which does good stuff.", rustdoc will incorrectly consider the 1st sentence to be "This is the foo library version 1.".

(I assume you meant that it should only end when the . is followed by a space; I amended the title to change ... is not followed ... :) )

Part of #8125. (@cmr, @Seldaek, any input?)

Right now rustdoc_web (the new docs) makes the cut between short description and the rest of the docblock at the first \n\n. The reason is that many functions have two sentence one-liner descriptions and splitting those really doesn't make sense IMO, but it's an easy fix if it's deemed that splitting at the first sentence boundary is better.

This is no longer relevant with rustdoc_ng. The detection of \n\n was implemented, and it appears to be working ok.

This can certainly be reopened if it's still a problem.
