[PATCH] git-send-pack: Fix --all option when used with directory

[Stanislav Kolotinskiy <stanislav@assembla.com>]

When using git send-pack with --all option
and a target directory, usage message is being
displayed instead of performing the actual transmission.

The reason for this issue is that refspecs variable is being
calculated in a different way comparing to previous versions,
and even though the number of refspecs (nr_refspecs) is 0,
refspecs contain all the arguments and switches passed to send-pack.

This ensures that send-pack will stop execution only when --all
or --mirror switch is used in conjunction with any refs passed.
