--- PrettyPrint.singleline_format([output[, maxwidth[, newline[, genspace]]]]) {|pp| ...}
#     is similar to PrettyPrint.format but the result has no breaks.
# 
#     maxwidth, newline and genspace are ignored.
#     The invocation of breakable in the block doesn't break a line and
#     treated as just an invocation of text.
