"man set" can't provide that information trivially without knowing your shell; dash/bash/ksh/zsh will all be subtly different.

However, if you are running bash, "help set" is fine.

FWIW, I really don't like pipefail as a default (e.g. piping to "head" causes random pipefails) and -e also has some confusing semantics. Also either failglob or nullglob are more important than either and -C is useful for some scripts as well.

[edit]

Simple example of confusing "set -e" semantics:

The following does not print "hi" and shows returns error status, as expected:

  (set -e; echo hi); echo $?

But put it in an if statement, and it's suddenly success, and does print hi:

  if (set -e; false; echo hi); then echo hello; fi

The same problem applies to functions. The below function will remove all files in the current directory if it's called from a conditional, but not otherwise!

  foo() {
    set -e
    cd /some_directory # set -e means we exit if this fails
    rm -rf *
  }

I think just defining a die() function and using it after any command that must succeed is more verbose, but less error prone:

  cd /some_directory || die "chdir failed"
  rm -rf *
