mkdir ~/"some directory with ()'s"

case 1, works:
cd ~
cd some<tab>
result: cd some\ directory\ with\ \(\)\'s/

case 2, works:
cd /home/<user>/some<tab>
result: cd /home/jeffm/some\ directory\ with\ \(\)\'s/

case 3, fails:
cd ~/some<tab>
result: cd ~/some\ directory\ with\ ()'s/
expected result: cd ~/some\ directory\ with\ \(\)\'s/

In case 3, the parens and the ' are not escaped, resulting in a syntax error
when the command is entered.

This bug is also present in SL9.3. tcsh works fine.
