Actually it does not work as documented. Even though the shell is
invoked the $ is escaped, thus no environment variables are expanded.
I can make this command work:
echo expand('$shell')
/bin/tcsh
However, if a file name contains a $ and what follows happens to be a
variable name, then you do not get that file name. I would think this
is OK, a $ should be escaped to avoid the expansion, right?
