sub-fetches discard --ipv4|6 option

[Alex Riesen <alexander.riesen@cetitec.com>]

Hi everyone,

I have a slight problem with IPv6 configuration in my local network (connect
works but transfers do not) and would like to temporarily disable use of the
transport for a series of fetches. The fetches are all done from within a
script to which I can pass options for "git fetch" commands in its
command-line. The options will be appended to the fetch commands, i.e.:

    git fetch <hard-coded-script-options> --ipv4

Unfortunately, it only worked for the fetches which didn't use --all or
--multiple. After a light searching, I failed to find an explanation as to
why --all|--multiple are handled so inconsistently with single remote fetches
and added the options (similar to --force or --keep) to the argument list for
sub-fetches:

diff --git a/builtin/fetch.c b/builtin/fetch.c
index 82ac4be8a5..5e06c07106 100644

 }
 
Am I missing something obvious?
