bug#5570: automatic cache validation

[Chong Yidong]

Hi Alan,

I found a small recipe for reproducing a (the?) cache bug on the trunk:

1. emacs -Q

2. C-x C-f foo.c RET

3. Type the following (from view-lossage):

  i n t SPC m a i n SPC ( ) <return>
  { <return> f o o ; <return> } M-< <return>
  <up> # i n c l u d e SPC < s t d i o . h > <return>
  <down> <down> <down> <tab>

At this point, the line "foo;" becomes indented to the zeroth column.

Does this help?
