Bug 0000249: Add standard support for $'...' in shell Reopened
http://austingroupbugs.net/bug_view_page.php?bug_id=249
We will return to bug 249 on a future call.

Richard has an action to propose new wording to discuss in a future telecon.
* Current Business
Bug 0001038: Specification relies upon unspecified behaviour Accepted as Marked
http://austingroupbugs.net/bug_view_page.php?bug_id=1038
An interpretation is required.
This item is tagged for TC3-2008
Interpretation response:
The standard states that "$ " is the
default PS1 prompt value and states that the behavior with this default
prompt is unspecfied. However, concerns have been raised about this
which are being referred to the sponsor.
Rationale:
This is not the way traditional and current shells behave and does
not accurately describe the way shells should behave.
Notes to the Editor (not part of this interpretation):
On page 2353 line 75012-75019 (2016 edition page and line numbers)
XCU section 2.6 (Word Expansions) change:
If an unquoted '$' is followed by a character that is not one of the
following:
[...]
the result is unspecified.
to:
If a '$' that is neither within single-quotes nor escaped by a <backslash>
is immediately followed by a character that is not a <space>, not a <tab>,
not a <newline>, and is not one of the following:
[...]
the result is unspecified. If a '$' that is neither within single-quotes nor
escaped by a <backslash> is immediately followed by a <space>, <tab>,
or a <newline>, the '$' shall be treated as a literal character.
Bug 1039: Which option flags should appear in $- ? Accepted as Marked
http://austingroupbugs.net/bug_view_page.php?bug_id=1039
An interpretation is required.
This item is tagged for TC3-2008
Interpretation response:
The standard states that $- includes the options set on the sh
command line, and conforming implementations must conform to this.
However, concerns have been raised about this which are being
referred to the sponsor.
Rationale:
Some existing shells do not include c or s in $-.
Notes to the Editor (not part of this interpretation):
On 2016 edition page 2350 line 74880 section 2.5.2, after:
(Hyphen.) Expands to the current option flags (the single-letter
option names concatenated into a string) as specified on
invocation, by the set special built-in command, or implicitly
by the shell.
add:
It is unspecified whether the -c and -s options are included
in the expansion of <tt>$-</tt>. The -i option shall be included
in <tt>$-</tt> if the shell is interactive, regardless of whether
it was specified on invocation.
Bug 1040: open_wmemstream() and mbstate_t Accepted
http://austingroupbugs.net/bug_view_page.php?bug_id=1040
This item is tagged for TC3-2008.
We discussed bugnote:3112, but decided no changes were needed because of it.
