bug#8027: 23.2; shell problem with $( and !!

From: relson
Subject: bug#8027: 23.2; shell problem with $( and !!
Date: Sat, 12 Feb 2011 20:32:16 -0500

In a shell window using "!!<tab>" when the previous command uses "$(
... )" improperaly adds a space between the "$" and the "(".

Starting with a directory containg a file named "test", here's how to 
demonstrate the problem:

1) In a shell window I can execute "find . -name test" and it'll find the 1
file that's truly in the current directory.

2) I can then execute 'ls -l !!<tab>' and the expansion will be "ls -l
`find . -name  test`" which is correct.

3) I can also execute 'ls -l $( find . -name test)` and the test file will
be correctly listed.

4) However, if I then type 'ls -l !!<tab>' the "$(" becomes "$ (" (with
a space in the middle), and the command fails.
