bash 4.2 patchlevel 28

[Sean Bruno]

Noted that the following syntax is broken somewhere between 4.2
patchlevel 10 and 28.  I'm sure its because we shouldn't be doing that
over here at big purple, but we do ... and its a PITA.  I'm bisecting to
find out what is going on.

test:
VARIABLE="$(uname)"
bash: command substitution: line 3: syntax error near unexpected token
`)'
bash: command substitution: line 3: `uname)"'

Odd, but his works at patchlevel 10
