Currently the file list generated by Doxygen has src/ at the
beginning of each path. Paths like common/sysdefs.h and
liblzma/api/lzma.h are easier to read without such a prefix.
Builds from a separate build directory with
mkdir build
cd build
../configure
doxygen Doxyfile
include an even longer prefix /home/someone/src/xz/src; this
patch has the nice side-effect of eliminating that prefix, too.
Fixes: http://bugs.debian.org/572273
lots of comments from Doxygen.
It seems that the Doxygen authors' intent is to not apply
their copyright on generated files, but since it doesn't
matter for XZ Utils at all, better safe than sorry.
