This line of reasoning makes me feel uneasy.

The approach may allow a directory that has "insane" tools in it to be on
the SANE_TOOL_PATH for *this* particular codepath, but at the same time,
it encourages people to build Git with such a broken SANE_TOOL_PATH.

Aren't you exposing your users to potential breakage in other parts of the
system, caused by broken tools on SANE_TOOL_PATH that is not shell, by
doing so?  Worse yet, there is no escape hatch similar to SHELL_PATH for
such tools.

Will queue on 'pu' for now, but I am not convinced.
