+- Update to 2.15:
+  Bug fixes:
+  * grep's \s and \S failed to work with multi-byte white space
+    characters.
+  * grep -i would segfault on systems using UTF-16-based wchar_t
+    when converting an input string containing certain 4-byte UTF-8
+    sequences to lower case.
+  * grep -E would segfault when given a regexp like
+    '([^.]*[M]){1,2}' for any multibyte character M.
+  * grep -F would get stuck in an infinite loop when given a search
+    string that is an invalid byte sequence in the current locale
+    and that matches the bytes of the input twice on a line.  Now
+    grep fails with exit status 1.
+  * grep -P could misbehave.
+
+  New features:
+  * grep -P can now use a just-in-time compiler to greatly speed up
+    matches, This feature is transparent to the user; no flag is
+    required to enable it.  It is only available if the
+    corresponding support in the PCRE library is detected when grep
+    is compiled.
+- require xz for SLE
+- require texinfo for makeinfo
+- don't autoreconf
+- remove the added german translations, upstream is up-to-date
