[PATCH v2] docs: link generating patch sections

From: John Cai <johncai86@gmail.com>

Currently, in the git-log documentation, the reference to generating patches does not match the section title. This can make the section "Generating patch text with -p" hard to find, since typically readers of the documentation will copy and paste to search the page.

Let's make this more convenient for readers by linking it directly to the section.

Since git-log pulls in diff-generate-patch.txt, we can provide a direct link to the section. Otherwise, change the verbiage to match exactly what the section title is, to at least make searching for it an easier task.

    Currently, in the git-log documentation, the reference to generating
    patches does not match the section title. This can make the section
    "Generating patch text with -p" hard to find, since typically readers of

    the section.
    
    Since v1:
    
     * added explicit anchor for generating patch text section
     * adjusted verbiage to include quotations
