| Options: |
/command - UNIX command to edit a file (default: see below)
/command can be either false or a string.
If /command is set to false, "edit" will issue a message that informs
about how to set the editor
If it is set to the name of a UNIX program, "edit" will execute
this program as a child process, passing the name of the
file as argument.
/command defaults to the contents of the $EDITOR environment
variable. If this variable is not set, it defaults to false.
/wait - whether to wait for the UNIX program to finish. (default: true)
If /wait is set to true, the "edit" command will not return until
the UNIX process is terminated. Use this setting for all editors
that use the terminal exclusively.
If /wait is set to false, "edit" will return immediately after
creating the child process. Use this setting for all editors that
open up their own window.
The value of /wait is ignored, if /command is set to false.
