[The following is an intelligent message.]
Fellas, I just got the message "Buffer XXX has shrunk a lot; auto save
turned off there".
OK,
1. looks like a pretty important message... what if I was doing a lot
of commands that involved the minibuffer, or else generally typing
fast... would there be a chance that I would have not noticed the
message? Maybe have it come up in a new minibuffer at the top of
the screen?
2. You assume that know what is right and throw autosaving to the
winds... it just so happens that I had inserted a large chunk of
text and then whittled it back down to size... Yes I then did M-x
auto-save-mode when I saw the above message, as there is no reason
that I don't want auto-save protection now that I've whittled it
back down to size...
3. OK, I see in Info that after a while auto-saving will be turned
back on, however, instead of throwing auto-saving to the winds
momentarily, why not save the former bigger file to a new secondary
auto-save file, and just continue the normal auto-saving to the
standard auto-save file. This has the bonus that auto-saving is on
at all times---we don't assume we are smarter than the user
anymore---also if indeed he did delete much valuable text, it still
will be somewhere instead of wiped out forever when autosaving gets
turned back on eventually under the current scheme.
I suppose when he does save the file we can dispose of all the auto
save files, however "text shrunk a lot since last save... leaving
secondary autosave file on disk" might be also good...
4. BTW, The current message "auto save turned off there" gives no
reassurance that the coverage outage is momentary, as mention only
in Info. Also it would be nice for the message to mention when
auto-saving will be turned back on so I know if I should bother
turning it back on manually.
5. Or maybe just suddenly ask the user "Hey, Charles, Buffer XXX has
shrunk a lot, Like, are you serious man? y/n"....
