    make(1): make ampersand in ${VAR:from=to&} an ordinary character

    In SysV substitutions, wildcards are expressed with % instead of &.  The
    & is not mentioned in the manual page, and having another wildcard for
    the whole word would be such an obscure feature that not even pkgsrc uses
    it.  The easiest way to discover this feature had been to read the source
    code of make(1) or to use a fuzzer and accidentally stumble upon this
    edge case.
