Summary 0000715: Typo in description of "set -e"
Description There appears to be a typographical error in the description of "set -e" in TC1,
at least in the HTML version:

    This requirement applies to the shell environment and each
    subshell environment separately. For example, in:

    set -e; (false; echo one) | cat; echo two

    the false command causes the subshell to exit without executing
    however, is executed because the exit status of the pipeline is zero.

The "Desired Action"
http://www.austingroupbugs.net/view.php?id=52 [^]
indicates the sentence should read:

    the false command causes the subshell to exit without executing
    echo one; however, echo two is executed because the exit status
    of the pipeline (false; echo one) | cat is zero.
Desired Action Use the text from 0000052.
Tags No tags attached.

 The text is correct in the PDF, so it's an HTML translation problem.
I have moved this bug to "Online Pubs".

 There is a similar problem for trap:

    "Implementations may check for this case using only lexical
    analysis; for example, if and do not alter the traps in the
    subshell, cases such as assigning and then using may still alter
    them."

In both cases there is some in-line constant width text in the PDF
that has gone missing in the HTML; looks like the converter is not
handling whatever the troff source is using to generate that.
