From: Haritha D <harithamma.d@xxxxxxx> This commit enables git to build on z/OS. It takes advantage of enahanced ASCII services on z/OS to auto-convert input files to ASCII It also adds support for [platform]-working-tree-encoding. Platform is substituted with uname_info.sysname, so it will only apply to the given platform. Also adds support for scripts that are not in standard locations so that /bin/env bash can be specified.
