Then you have GPLv3.  Question is whether the common portion comes from
this script?  If yes, then we consider LGPL versus everything being
GPLv3.

This seems pretty unlikely as this is a rather specific task.
`git fast-import` isn't likely to be useful in very many places.  Also,
`git` isn't something I would expect to see on a 128MB RAM device.

This is very well-understood.  GPL applies to source code and the tools.
GIMP is routinely used to produce non-GPL images.  `git` is now used by
MS for handling their source code, most of it remains non-GPL and no
lawsuits have resulted.  GCC is routinely used to build non-GPL software.

Anything not directly linked in is completely uneffected.  In particular
while it does manipulate git's data, none of that is linked into the
script and therefore has no license effects.  This won't have any
particularly notable effects.
