[PATCH v2] push: Re-include "push.default=tracking" in the documentation

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Change the documentation for push.tracking=* to re-include a mention
of what "tracking" does.

The "tracking" option was renamed to "upstream" back in
53c4031 ("push.default: Rename 'tracking' to 'upstream'", 2011-02-16),
this section was then subsequently rewritten in 87a70e4 ("config doc:
rewrite push.default section", 2013-06-19) to remove any mention of
"tracking".

Maybe we should just warn or die nowadays if this option is in the
config, but I had some old config of mine use this option, I'd
forgotten that it was a synonym, and nothing in git's documentation
mentioned that.

That's bad, either we shouldn't support it at all, or we should
document what it does. This patch does the latter.

And neither was I it would appear, and for a much longer time...

Makes senes. Here's a re-send that fixes this. I slighly changed the
wording you suggested to be consistent with the other existing cases
in config.txt:
    
    5 matches for "eprecated.*for" in buffer: config.txt
       2328:	This is a deprecated synonym for `repack.writeBitmaps`.
       2462:* `tracking` - This is a deprecated synonym for `upstream`.
       2813:	Deprecated alias for 'sendemail.smtpEncryption = ssl'.
       2853:	Deprecated alias for `sendemail.signedoffbycc`.
       3180:	Deprecated alias for `versionsort.suffix`.  Ignored if
