# Support routines for hand-crafting loose objects.
# Write a loose object into the odb at $1, with object type $2 and contents
# from stdin. Writes the oid to stdout. Example:
#
# oid=$(echo foo | loose_obj .git/objects blob)
#
loose_obj () {
cat >tmp_loose.content &&
size=$(wc -c <tmp_loose.content) &&
{
# Do not quote $size here; we want the shell
# to strip whitespace that "wc" adds on some platforms.
