No word splitting for assignment-like expressions in compound assignment
Hello!
I have a question about the following behavior:
$ Z='a b'
$ A=(X=$Z)
$ declare -p A
declare -a A=([0]="X=a b")
$ A=(X$Z)
$ declare -p A
declare -a A=([0]="Xa" [1]="b")
I find it surprising that no word splitting is performed in the first
compound assignment. I realize that skipping word splitting may be
desirable if a subscript is given (e.g. "A=([0]=$Z)") to make it
consistent with normal variable assignment[1], but in this case it looks
like a bug.
I've reproduced the described behavior on bash 4.4.20 (Ubuntu 18.04),
3.1.17 (CentOS 5) and self-built 5.1-alpha release.
Some other discoveries:
* Brace expansion is performed for "A=(X=a{x,y}b)" by all bash versions
mentioned above (which is inconsistent with normal variable assignment).
* Globbing for "A=(X=a?b)" is performed by bash 3.1.17, but not by other
versions.

EOF not disabled in readline
It seems that disabling the EOF character does not have an effect on
readline. For example:
$ stty sane
$ stty eof undef
$ ^D
Use "logout" to leave the shell.
$ read -e; echo $?
^D
1
But the setting did take effect, as can be verified by running, e.g.
`read' w/o readline:
$ read -n1; echo ${REPLY@Q}
^D$'\004'
Setting the EOF character to anything else works as expected but, when
followed by an `stty eof undef', readline keeps using whatever the value
that had previously been set.
My goal was to bind a custom function to ^D and, as a workaround, setting
EOF to some nearly-impossible to type character works fine but I'm not
sure if the inability to disable EOF is expected.
$SHELLOPTS after function with `local -'
The value of $SHELLOPTS is not always updated correctly after returning
from a function that modifies options after using `local -'.
For example:
fun() { local -; set -u; }; fun
[[ $- == *u* ]]; echo $?# 1
[[ :$SHELLOPTS: == *:nounset:* ]]; echo $? # 0
This seems to be the case for the following set of options:
interactive-comments, keyword, monitor, noclobber, noglob, nolog, notify,
nounset, onecmd, physical, pipefail, privileged, verbose, xtrace
While it works correctly for:
allexport, braceexpand, emacs, errexit, errtrace, functrace, hashall,
histexpand, history, ignoreeof, noexec, posix, vi
$IGNOREEOF always modified by `local -'
Having IGNOREEOF defined prior to invoking a function that uses `local -'
causes IGNOREEOF to be set to `10' after the function returns.
$ IGNOREEOF=0; f() { local -; }; f; echo $IGNOREEOF
10
