shell-expand-line drops quotation marks

[Keith Thompson]

The shell-expand-line command (bound to Escape-Ctrl-E) incorrectly removes quotation marks from

the command line, often resulting in a command that differs from what the user intended to type.

I've seem this problem with all recent versions of bash, particularly 4.3.11 (preinstalled on

Linux Mint 17.2) and 4.4-beta (built from source on the same system).

Here's a demonstration:

$ /bin/bash --norc

bash-4.3$ uname -a

Linux bomb20 3.16.0-38-generic #52~14.04.1-Ubuntu SMP Fri May 8 09:43:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

bash-4.3$ echo $BASH_VERSION

4.3.11(1)-release

bash-4.3$ bind -p | grep shell-expand-line

"\e\C-e": shell-expand-line

bash-4.3$ echol() { for word in "$@" ; do echo "$word" ; done ; }

bash-4.3$ echo foo bar

foo bar

bash-4.3$ echol 'string with spaces' !*     # Here I typed just the command you see; it worked.

echol 'string with spaces' foo bar

string with spaces

foo

bar

bash-4.3$ echo foo bar

foo bar

bash-4.3$ echol string with spaces foo bar  # Here I typed the same command, then Escape-Ctrl-E

string

with

spaces

foo

bar

bash-4.3$

I often type Escape-Ctrl-E to expand a history substitution in place

before typing Enter, but it has the side effect of stripping quotes from

what I've already typed.
