Here's where I go "huh." That works, but 1) I don't at all get how
the input is passed to the command; and 2) if I call on STDIN.read

input), then that line fails to get any input, and I have to
manually pipe the text back into it. What's happening there?
Well, if you call read(), you consume the input, so it's not there
to pass on to the child process.
I was guessing that was the case. But how about the first question,
if there is input how does that statement suck it up automatically?
(Apologies if this is excruciatingly basic; I'm just trying to
understand how the input gets passed without explicitly doing so.)
Hmm, I think you are still having trouble
understanding where to
e_sh(): for data headed to the shell
Aha, now that I know there's e_sh(), I do understand it. Thanks :)
Here's the code I just moved into the Source
bundle. Let me know
if this is working please:
It looks like it works well for most cases, but I think the more
lenient regex causes a problem in the case of a latex comment such as
"%\usepackage" (note no space); in that case, the comment parameter
is set to "%\" and the backslash ends up causing problems.
