When we execute commands from a shell script, make sure that the signals
...
are being caught (reported by Alexis Rosen), similar to the -c case.
#!/bin/sh
vi "$@"
^C when the script is running...

The builtin . (dot) command no longer sees the current working directory
...
even if the specified file is not in the PATH.
This change enforces security and makes it conform to POSIX.
Closes PR #6794 .
I thought Christos committed this but not appeared yet. :)
The setstackmark()/popstackmark() pair in dotcmd(), used for freeing
stack storage possibly allocated by find_dot_file(), is redundant for now
since dotcmd() is surrounded by another pair in evalcommand().
This redundancy, however, may help future modifications
(suggested by Christos).

Fix PR/1760, where 'cd -' before any other command could cause a reference

Fix return builtin to work like it does in ksh:

When not in a function, it skips the rest of the current input file.
Instances of `return' outside function definitions were previously ignored.

are honored during and after the execution of the script.
