Bug#794965: Dash fail to remove trailing spaces.

[Bize Ma]

Package: dash
Version: dash: 0.5.7-3

This two commands:

dash -c 'echo "    a b     " | { read var; echo "<$var>"; }'
bash -c 'echo "    a b     " | { read var; echo "<$var>"; }'

produce:

<a b     >

<a b>


So, dash is not ignoring trailing spaces of values as defined in POSIX
(and most shells do):

   -  The remaining fields and their delimiters, *with trailing **IFS
white space ignored*


Even with a confirmed default value of IFS:

    $ printf "%s" "$IFS"|xxd -p
