Bug #4859: exec regression - shell negation doesn't work anymore

In 0.25.5 and previous, you can no longer use shell negation on commands. I use
these in 'onlyif' statements for some.
Here's a sample reproduce case:
<pre>
class foo {
Exec {
path => [ "/bin", "/sbin", "/usr/bin", "/usr/sbin",
"/usr/local/bin", "/usr/local/sbin" ],
}
exec {
"echo hello world":
onlyif => "! false";
}
}
include foo
</pre>
This works in previous versions (<= 0.25.5). In 2.6.1, this does not work.
Specifically, this line causes the error:
<pre>
onlyif => "! false";
</pre>
It also fails if the '!' appears first in the actually command name (like "!
echo hello world").
Failure from 2.6:
<pre>
% puppet apply --verbose test.pp
info: Applying configuration version '1285645441'
err: /Stage[main]/Foo/Exec[echo hello world]: Could not evaluate: Could not
find command '!'
</pre>
Success on 0.25.5:
<pre>
% puppet --verbose test.pp
info: Applying configuration version '1285645456'
</pre>
There are workarounds, like adding `[ \$? -ne 0 ]` -
<pre>
onlyif => "false; [ \$? -ne 0 ]"
</pre>
