This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at
debbugs.gnu.org. Please check that
the From: line contains a valid email address. After a delay of up
to one day, you should receive an acknowledgment at that address.
Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.
Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe
starting from `emacs -Q':
- start emacs 24.3 with -Q (note: emacs 24.1 also shows the same behaviour)
- make the following file and call it "file-abbbb" (insert the broken bar with C-x 8 RET a6 RET):
line with ¦ (broken bar character)
bla
bla
bla
bla
- remove the last "bla" and write that as "file-abbb"
- again and write as "file-abb"
- set diff executable to msysgit 1.8.1.2 in customize Diff Command
"C:/Program Files/Git/bin/diff.exe"
- diff file-abbb with file-abb respectively file-abbbb (using "=" in Dired):
the first diff shows ^M's at the end of the lines from the files
(but not at the end of the lines from diff itself, the headers etc.),
but the second diff shows no ^M's.
- in the second case the broken bar non-ascii character is inside
of the context of the change, whereas in the second case is outside
of the context of the change and therefore not present in the diff
buffer.
(By the way: these different behaviours cause problems with magit:
without the ^M's it is not possible to stage a region of a hunk,
with the ^M's it does work. Normally I would prefer the ^M's to be
absent.)
Why is this behaviour dependent on the presence of a non-ascii character?
Thanks in advance,
Albert.
