Bug in 'histreduceblanks' w.r.t. multi-line commands

[Hans Meine <hans_meine@xxxxxxx>]

Hi,

with the histreduceblanks option enabled, I suffered from the problem that multi-line commands like the following were mangled in the history:

cd ~/Developer && \
svn up --accept postpone -r190973 MeVisLab MeVis/Foundation && \
svn up --accept postpone -r197619 FMEwork FMEstable

The command appears in history totally broken, with missing and duplicate/substituted parts as follows:

cd ~/Developer && n n up -cceptpt ptponene -9097373 MisLabab Mis/Foundationon && svn up -eptcept ponepone -6197619 ork ork FMbltable

Interestingly, when trying to simplify this example, I noticed that the following works:

cd foo && \
ls  && \
echo bar   

I did create a new user for testing and could verify that this is not caused by a conflict with any of the other options that I enabled; even with the default config (or no_zle etc.), the problem starts to appear as soon as I enable histreduceblanks.

Best regards
  Hans
