518d8dd979 eliminated CONFIG_FEATURE_EDITING_FANCY_KEYS. the size savings
was small, compared to the total size of the command-line editing
features, and it removed key bindings that most wouldn't consider
"fancy", like ^U, and 'l' and 'h' in vi mode, ^F and ^B in emacs
mode.

84bbac5a09 enable use of ^V prefix to allow forced insertion of any character. in
particular, without this it's impossible to enter a TAB on the commandline
(whether tab completion is enabled or not).

abee3d0e0d Fix xmalloc_fgets_str so that it really does NOT strip terminator.
Add xmalloc_fgetline_str which does strip terminator,
and use it in dpkg instead of xmalloc_fgets_str.
netstat: use xmalloc_fgets_str - allows to eat strings with NULs
