Survey on use of \";\" \"&&\" \"||\" to separate shell commands.

[Doug Gwyn (VLD/VMB)]

I use && and || a lot.  I NEVER expect any command to fail except
via a nonzero exit code.  Any significant task I do with a shell
script, and if signals etc. matter then I intercept them.  Things
like "a && (b ; c)" work very nicely but one rarely requires them.
I think too much ado is being made over this issue.
