[PATCH] git fetch: Take '-n' to mean '--no-tags'

[Andreas Ericsson <ae@op5.se>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

Prior to commit 83201998730ac5f0b95ac832f3b727da26ab0129, we
understood '-n' as a short option to mean "don't fetch tags
from the remote". This patch reinstates behaviour similar,
but not identical to the pre commit 832019987 times.

Back then, -n always overrode --tags, so if both --tags and -n
was given on command-line, no tags were fetched regardless of
argument ordering. Now we use a "last entry wins" strategy,
so '-n --tags' means "fetch tags".
Since it's patently absurd to say both --tags and --no-tags
this shouldn't matter in practice.
