The string returned by the tt(format) style (if any) will be modified so
that the sequence `tt(%d)' is replaced by the var(descr) given as the third
argument. If tt(_description) is called with more than three arguments,
argument without any leading or trailing white space. If, after
removing the white space, the var(descr) is the empty string, the format
style will not be used and the options put into the var(name) array will
not contain an explantion string to be displayed above the matches.If
tt(_description) is called with more than three arguments,
the additional var(specs) should be of the form `var(char)tt(:)var(str)'
and every appearance of `tt(%)var(char)' in the format string will be
replaced by var(string).
