I revisited the patch posted there to allow -j without sh.exe, and I'm
afraid I don't understand the patch. It does this:
. add "^()" to sh_chars_dos[] in job.c
. use '^' to escape special characters such as \ and " in job.c
. removes the code fragment in main.c that forces job_slots = 1 if
sh.exe is not available
Can someone please explain which part(s) of this patch solve(s) the
original problem? For that matter, what shell features are required
to enable -j on Windows, and why?
Paul, it sounds like I'm confused about how -j works and interacts
with the shell--can you please clarify this for me?
In this message:

Paul refers to "a bunch of discussion about this one by Eli etc.", but
I cannot find these discussions in the archives. If they shed some
light on the issue at hand and especially on the suggested patch,
please point me to those discussions, so I could re-read them.
I'm willing to add the code that will enable -j only if the version of
cmd.exe is new enough to support it, but to do that, I need first to
understand the details of the problem and how the suggested patch
tries to resolve it. TIA.
