[PATCH] docs: link generating patch sections

[John Cai via GitGitGadget]

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.

Is this "prepend underscore, downcase, and replace each run of
non-alnum with an underscore" ASCIIDoc magic?  AsciiDoctor magic?
All such backends prepare the anchor in the same format?

I am mostly worried about relying on automatic magic that can
silently be broken when say the title in diff-generate-patch.txt
file is improved.  Whoever is updating the file would not know
it is being referenced from elsewhere (and it is hard to check).

Or perhaps you forgot a single liner patch to diff-generate-patch.txt
that adds [[_generating_patch_text_with_p]] anchor yourself?

The capitalization makes it look somewhat odd in the resulting
text.  Quoting, e.g.

	see the section titled "Generate patch text ..."

may make it acceptable, though.

Yes, I believe this is asciidoc magic.

Good point, adding an explicit anchor makes sense.

yeah I agree here--I can adjust this in the next version

thanks
