Subject: Fix bug #9139 with revisiting non-existent files.
X-Git-Tag: emacs-pretest-24.0.90~104^2~97
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=b885bf36cf2c7f79517a1c797fd09e7adc3358c6;p=emacs.git

Fix bug #9139 with revisiting non-existent files.

 src/fileio.c (Finsert_file_contents): If the file cannot be opened,
 set its "size" to -1.  This will set the modtime_size field of
 the corresponding buffer to -1, which is what
 verify-visited-file-modtime expects for files that do not exist.
