When using an external editor (i.e. "Use internal edit" in the Configure
Options is unchecked) the environment variable EDITOR is used. However,
if $EDITOR contains a command line argument after the executable name,
these arguments are not processed properly, and the editor might not be
started at all.
How to reproduce: (Precondition: vi is available on the system)
1) On the command line, execute: export EDITOR="vi +" && mc
(the + argument should let vi start at the document's end instead of the
beginning).
2) Go to the Options menu -> Configuration -> uncheck "Use internal
edit".
3) Move the cursor to a file that is larger than a single screen (e.g.
ABOUT-NLS in mc's source directory).
4) Press F4 to start the external editor.
Result: Nothing visible happens
Expected result: vi is opened showing the end of the file ABOUT-NLS
The bug: my_system_make_arg_array() doesn't perform full-feature
parsing of the comman line.
