+- Update to 2.13:
+  It's moderately important to upgrade from grep-2.6 or newer,
+  since a Turkish I-with-dot (U+0130) on a matched/printed line
+  makes "grep -i" (in nearly any UTF-8 locale) emit corrupt output.
+  Bug fixes:
+  * grep -i, in a multi-byte locale, when matching a line
+    containing a character like the UTF-8 Turkish I-with-dot
+    (U+0130) (whose lower-case representation occupies fewer
+    bytes), would print an incomplete output line. Similarly,
+    with a matched line containing a character (e.g., the Latin
+    capital I in a Turkish UTF-8 locale), where the lower-case
+    representation occupies more bytes, grep could print garbage.
+    [bug introduced in grep-2.6]
+  * --include and --exclude can again be combined, and again
+    apply to the command line, e.g., "grep --include='*.[ch]'
+    --exclude='system.h' PATTERN *" again reads all *.c
+    and *.h files except for system.h.
+    [bug introduced in grep-2.6]
+  New features:
+  * 'grep' without -z now treats a sparse file as binary,
+    if it can easily determine that the file is sparse.
+  Dropped features:
+  * Bootstrapping with Makefile.boot has been broken since
+    grep 2.6, and was removed.
