The file texinfo-4.13-lzip.tar.lz is an update adding lzip support to http://ftp.gnu.org/gnu/texinfo/texinfo-4.13a.tar.gz. The changes with respect to texinfo-4.13a are minimal (the diff is 166 lines long). If anybody is interested, I have made a broader update that in addition to lzip support also fixes quoting in the creation of info and html files ('like this' instead of `like this'), uses the '.texi' extension for texinfo files instead of '.txi' (as recommended by automake), adds '-V' as synonym of '--version' to the info reader, removes the dependency on pure decompressors (gunzip, bunzip2), and fixes some warnings with modern gcc. A sample of the output of the patched makeinfo can be seen at http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html
