so Windows programs can't be written to read from STDIN? I can't think of any Unix utility that uses commas to delimit. And any Windows one that uses commas is clearly improper/wrong was well.
If "you're not supposed to invoke setup.exe from within cygwin" were true then all the 'xargs' and 'paste' workarounds are null and void. And no, I don't automatically reach for xargs to bandaid around poorly written programs that violate 50 years of convention.
