Subject: HIST_IGNORE_DUPS also ignores command lines that differ by a space between quotes
Date: Wed, 13 Mar 2024 13:38:17 +0100	[thread overview]
Message-ID: <20240313123817.GA3492761@cventin.lip.ens-lyon.fr> (raw)

With zsh 5.9, HIST_IGNORE_DUPS is buggy: it also ignores command lines
that differ by a space between (single or double) quotes.

For instance, with

  setopt HIST_IGNORE_DUPS
  echo " "
  echo "  "

(the first echo with only 1 space character between the quotes,
the second echo with 2 space characters between the quotes), zsh
keeps only the second one in the history.

Such spaces are significant, so that these command lines are not dups.

However, if the spaces are quoted, this problem does not occur:

  echo \ .
  echo \ \ .
