Re: [PATCH v2] expand: Fix multiple issues with EXP_DISCARD in evalvar

[Martijn Dekker]

I encountered another bug, introduced by 3cd5386 and not fixed by v2 of 
this patch: the presence of a length-counting expansion like ${#foo} in 
a string causes the rest of the string to be discarded.

$ src/dash -c 'foo=bar; echo "baz ${#foo} quux"'
baz 3
$ src/dash -c 'foo=bar; echo baz\ ${#foo}\ quux'
baz 3
(expected outout: baz 3 quux)
