Subject: PATCH: 3.0.6-pre-3: parameter fixes
Date: Tue, 01 Jun 1999 13:25:33 +0200 [thread overview]
Message-ID: <9906011125.AA14818@ibmth.df.unipi.it> (raw)
These are the two parameter fixes adapted for 3.0.6: first, typeset -m
restored unset parameters which hadn't been removed from the table; second,
in fn1() { local foo; unset foo; foo=bar; }, foo is restored at local
level, while if the `unset foo' appeared in a nested function it would have
been restored at global level, which is presumably wrong, depending what
`wrong' means.
