From 5ec8274b8424f76bf998059e66facff1b241337e Mon Sep 17 00:00:00 2001 From: Stefan Beller Date: Wed, 25 Oct 2017 11:49:11 -0700 Subject: xdiff-interface: export comparing and hashing strings 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.
