...sets implicit variable REPLY, even though ASH_BASH_COMPAT is not
That was introduced in 2010-01-12 with commit
045f4ad92c07434625e168bc8c37aa0e89f6e58e. The comment is still
present in the code:
+ /* $IFS splitting. NOT done if we run "read"
+ * without variable names (bash compat).
+ * Thus, "read" and "read REPLY" are not the same.
Still, this is a bashism and should be tested with IF_ASH_BASH_COMPAT.
Dash does not support that:
dash: 1: read: arg count
and The Open Group Base Specifications Issue 6 does not document that
Yes, I suspect the "feature" may be already abused.
What do you think?
