[Pkg-zsh-devel] Bug#705555: zsh: HIST_IGNORE_DUPS ignores lines which differ by a different number of spaces

[Vincent Lefevre]

Package: zsh
Version: 5.0.2-2
Severity: minor

Consider:

% setopt HIST_IGNORE_DUPS
% echo " "
% echo "  "

If I type the up arrow, I get

  echo "  "

as expected, but if I type the up arrow a second time, I get

  setopt HIST_IGNORE_DUPS

instead of

  echo " "

and:

% history
    1  setopt HIST_IGNORE_DUPS
    2  echo "  "
