[Nano-devel] [BUG] Undo and the 'modified' state issue

[Liu Hao]

nano does not update the 'modified' state if the file is saved after
modification.

Steps to reproduce:

1. Create an empty file.
2. Type `aaa` in then press <Enter>. The indicator in the upper right
   corner now says 'Modified'.
3. Press ^O and save the file somewhere, for example, `/dev/null`. The
   indicator disappears.
4. Type `bbb` in, The indicator says 'Modified' again.
5. Press M-U. This undoes the input and effectively restores the file
   to its last saved state, *but the indicator still says 'Modified'*.
6. Press M-U repeatedly until there are no more characters in the
   editing area. This restores the file to the state when it was opened.
   The indicator disappears, *but it shouldn't*.
