commit 4eba3234d09fc92de48748ed4bbf36303e3f5bf1
Author: Ingo Schwarze <schwarze@openbsd.org>

    [doc] delete redundant "SUFFIXES +=" line
    
    The .xhtml suffix is never used by anything, and automake(1)
    automatically generates all the others from the various suffix
    rules found in the various *.am files around the tree.
    
    Not trying to second-guess automake(1) provides two advantages:
    The "SUFFIXES +=" line can no longer become stale (like it did
    with .xhtml) and the generated Makefile gets minimally more readable
    and less confusing - even though admittedly, there are many reasons
    why the generated Makefile remains hard to read and debug anyway.
    
    No functional change.
    
    OK gbranden@
