Syntax: Modified [0|1]
Abbreviation: MOD
sets the modified flag. This flag is set automatically
whenever a document is modified, and is used to determine which documents
need to be saved by SaveAll or when ne exits. Normally you would not alter
this flag, but when a document is inadvertently modified and you don’t
want the changes saved, Modified provides a way to make
ne consider the document unchanged.
If you invoke Modified with no arguments, it will toggle the flag.
If you specify 0 or 1, the flag will be set to false or true,
respectively. An asterisk (‘*’) will appear on the status bar when
this flag is set. If your terminal supports underlining, it will be underlined
if the corresponding file’s modification time has changed since the document
was loaded or saved (perhaps by another user).
