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.

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.
