Path-mtu-discovery is described in rfc-1191 and some problems with it
in rfc-2923. The symtoms described in <attached email> is matches
"black hole" in rfc-2923.

It should be wholly agnostic to the "git fetch --depth 1" vs.
"git clone" choise. The "black hole" problem happens only for large
packets.

******
If it is the "black hole":

The best fix is to correct your router, setting the mtu in the router
might be a solution for that, but your router should return
a proper icmp error response (ICMP Destination Unreachable messages
with a code meaning "fragmentation needed and DF set") if the packet is
too large. Make sure the router and your host don't filter out thoose
icmp packets.

///

The second best is to send smaller packets from your host going through
that route. This can be set with 

 route del default gw <your router>
 route add default gw <your router> mss <some value>

where mss = maximum segment size. A good first try is MTU - 80, see 
rfc-879 for details.
