$ some_function() { echo foo; }
$ export -f some_function
Debian/sid (with shellshock patches):
$ bash --version
GNU bash, version 4.3.27(1)-release (x86_64-pc-linux-gnu)
[...]
$ env
[...]
some_function=() { echo foo
}
[...]
Debian/wheezy (with shellshock patches):
$ bash --version
GNU bash, version 4.2.37(1)-release (i486-pc-linux-gnu)
$ env
[...]
BASH_FUNC_some_function()=() { echo foo
}
[...]
Not nice :-/. So we need to convert 'BASH_FUNC_<something>()' ->
'<something>' before calling 'unset'.
