Bash Version: 3.2
Patch Level: 17
Release Status: release

Description:
sometimes an instance of bash starts to append a / to every command 
or file name completion instead of a space character.

I don't know what triggers this problem since it happens only
every few weeks -- but it shows up for quite a long time now.
comparing output of env/set/bin/complete never showed any 
significant difference between bad/good shells.


yesterday the /-problem showed up again and I started to debug
what's going on:

sometimes 'rl_completion_append_character' will be set to '/'
and it never will be reset back to ' ' :

        atuin bash-3.2 > grep -r rl_completion_append_character . 
==>     ./lib/readline/complete.c:int rl_completion_append_character = ' ';
        ./lib/readline/complete.c:  else if (rl_completion_suppress_append == 0 
&& rl_completion_append_character)
        ./lib/readline/complete.c:    temp_string[temp_string_index++] = 
rl_completion_append_character;
        ./lib/readline/readline.h:extern int rl_completion_append_character;
        ./lib/readline/readline.h:   rl_completion_append_character will not be 
appended. */
==>     ./bashline.c:   rl_completion_append_character = '/';


so far I don't understand how to trigger the change of 
rl_completion_append_character
in bashline.c (I really would like to know which operation triggers that bug!!)
and I'm not familar with the internal structures of bash to make 
a good guess where/when this variable should be reset to ' '
for the next completion operation (or, if it ever should be changed to / at all 
?!)

Repeat-By:

set rl_completion_append_character to '/' -- no idea how to trigger that 
directly



I _really_ would love to get rid of that annoying bug!!!


thanks for any help or fix!!
