564d19e3bd The ability to switch to sh for processing files starting with a ':' broke
recently, as the incorrect arguments were being passed to execve. The
function went through the trouble of creating the proper arguments, and
then failed to use them.

edc20a7505 Update to the ':' patch by Nicholas Burlett. This patch makes sure that ':' style executing of a command is only performed if a regular call to execve fails. This should improve performance a mall bit in the common case.

23759e6eca colon-command support
Shells such as bash, sh, tcsh, and ksh each support a "colon command" that causes the script to be
evaluated as a bourne script. In the case of bash and sh, this command is a no-op. For others,
it means the script has sh syntax.

To suppor this in fish, I've added code to launch_process that checks for a ':' as the first
character of p->actual_cmd. If it is a colon, the process descriptor is modified to call
/bin/sh, which should exist on any POSIX system.
