Documentation: describe subject more precisely
The discussion of email subject throughout the documentation is misleading; it indicates that the first line will always become the subject. In fact, the subject is generally all lines up until the first full blank line. This patch refines that, and makes more use of the concept of a commit title, with the title being all text up to the first blank line.

By default, the subject of a single patch is "[PATCH] First Line" and
|

the subject when multiple patches are output is "[PATCH n/m] First

Line". To force 1/1 to be added for a single patch, use `-n`. To omit

patch numbers from the subject, use `-N`.
|

By default, the subject of a single patch is "[PATCH] " followed by

the concatenation of lines from the commit message up to the first blank
|

line (see the DISCUSSION section of linkgit:git-commit[1]).

When multiple patches are output, the subject prefix will instead be

"[PATCH n/m] ". To force 1/1 to be added for a single patch, use `-n`.

To omit patch numbers from the subject, use `-N`.
