is another problem that causes bash to look up the wrong variable name when

There is a problem with unsigned sign extension when attempting to reallocate
the input line when it is fewer than 3 characters long and there has been a
history expansion. The sign extension causes the shell to not reallocate the

Bug-Description:
Patch (apply with `patch -p0'):
This patch changes the behavior of programmable completion to compensate
for two assumptions made by the bash-completion package. Bash-4.3 changed
to dequote the argument to programmable completion only under certain
circumstances, to make the behavior of compgen more consistent when run
from the command line -- closer to the behavior when run by a shell function
run as part of programmable completion. Bash-completion can pass quoted
arguments to compgen when the original word to be completed was not quoted,
expecting programmable completion to dequote the word before attempting
completion.
This patch fixes two cases:
1. An empty string that bash-completion passes to compgen as a quoted null
string ('').
2. An unquoted word that bash-completion quotes using single quotes or
backslashes before passing it to compgen.
In these cases, since readline did not detect a quote character in the original
word to be completed, bash-4.3
