e54ce9a147 Minor bug fix - the parse_util_set_argv function can trigger an event, hence signals have to be unblocked when it is called.

79ac330afb There code for detecting when a keepalive process was needed missed lots of cases. This should fix some issues. Both the keepalive code and the code for spawning fake processes for builtins should be rethought, though.

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.
