[PATCH v1] docs: submitting-patches: make section on linking more explicit

[Thorsten Leemhuis <linux@leemhuis.info>]

Mention the 'Link' tag in the section about adding URLs to the commit
msg, which makes it easier to find their meaning with a text search. For
the same reason and to improve comprehensibility also provide an
example.

Slightly improve the text at the same time to make it more obvious
developers are meant to add links to issue reports in mailing list
archives, as those allow regression tracking efforts to automatically
check which bugs got resolved.

Move the section also downwards slightly, to not jump back and forth
between aspects relevant for the top and the bottom part of the commit
msg.

Lo! The regression tracking bot I'm working on can automatically mark
entries as resolved, if a commit message uses a 'Link' tag to the
report.  Many developers already add them, but it afaics would improve
matters to make this more explicit. Especially as I had missed the
section about it myself at first, as I simply grepped for 'Link:' and
only found an explanation in configure-git.rst.

Konstantin, let me known if I should do a
s!lkml.kernel.org/r/!lore.kernel.org/r/! at the same time. If it is a
good idea, I'll prepare a second patch that does this here and other
places refering to lkml.kernel.org/r/ in a similar fashion.

Ciao, Thorsten
