This does not actually add newlines to the resulting string, as you see.

I hope I don't have code formatting practices imposed on my scripts... in my experience enforced formatting practices usually make things less readable and harder to edit.
I am actually well aware of that except I was wondering if the parser would chop at exactly 80 characters of which case the could corrupt the data if in mid flight inside a 4 character '\x??' string.

I treid it and it does corrupt.
Code:
printf "%b" "\x52\x49\x46\x46\x24\x00\x01\x00\x57\x41\x56\x45\x66\x6d\x74\x20\\
x10\x00\x00\x00\x01\x00\x01\x00\x40\x1f\x00\x00\x40\x1f\x00\x00\x01\x00\x08\x0\
0\x64\x61\x74\x61\x00\x00\x01\x00" > /tmp/binary

GIT-MERGETOOL--LIB(1)						    Git Manual						     GIT-MERGETOOL--LIB(1)

NAME

       git-mergetool--lib - Common git merge tool shell scriptlets

SYNOPSIS

       TOOL_MODE=(diff|merge) . "$(git --exec-path)/git-mergetool--lib"

DESCRIPTION

       This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the Porcelain-ish
       scripts and/or are writing new ones.

       The git-mergetool--lib scriptlet is designed to be sourced (using .) by other shell scripts to set up functions for working with git merge
       tools.

       Before sourcing git-mergetool--lib, your script must set TOOL_MODE to define the operation mode for the functions listed below. diff and
       merge are valid values.

FUNCTIONS

       get_merge_tool
	   returns a merge tool.

       get_merge_tool_cmd
	   returns the custom command for a merge tool.

       get_merge_tool_path
	   returns the custom path for a merge tool.

       run_merge_tool
	   launches a merge tool given the tool name and a true/false flag to indicate whether a merge base is present.  $MERGED, $LOCAL, $REMOTE,
	   and $BASE must be defined for use by the merge tool.
