This will turn out to be useful in a later patch. xdl_recmatch is exported in xdiff/xutils.h, to be used by various xdiff/*.c files, but not outside of xdiff/. This one makes it available to the outside, too. While at it, add documentation. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
