Title:
Multiline copy including comments cause trailing whitespace to be
pasted
Status in An Emacs mode for editing Python code:
Fix Released
Status in “emacs23” package in Ubuntu:
Fix Released
Bug description:
Binary package hint: emacs23
Steps to reproduce:
0. sudo apt-get install emacs23-nox
1. Remove any ~/.emacs customizations
2. In xterm or gnome-terminal, run /usr/bin/emacs foobar.py
3. Type in "# foobar" and hit enter
4. Triple-click the line
5. In some other editor (nano, gedit, pico, firefox textarea) paste text
Expected: "# foobar"
Actual: "# foobar
" # terminal-width amount of spaces
It seems to occur not just with python files but also C or perl. It
does not seem to occur with plain text files.
Interestingly, if you paste into emacs with python-mode enabled, it
will correct the trailing whitespace on paste. Even more interesting,
if you start in python-mode, tripleclick "# foobar", then M-x perl-
mode, and paste in the same buffer, it pastes the extraneous trailing
whitespace. (But vice-versa doesn't seem to trigger it.)
This occurs for me with both emacs22-nox and emacs23-nox, as well as
"emacs22 -nw" and "emacs23 -nw". It does not happen with Xemacs (or
at least, I couldn't get it to reproduce).
I've reproduced it on maverick, lucid, and karmic. I seem to recall
it didn't occur with earlier versions of emacs although I don't
remember if it was emacs22 or emacs21 that I first noticed it.
I've also tested an alternate python mode, but it shows the same
problem so I don't think this issue is particular to python-mode.el,
especially since I can reproduce the issue with C and perl files.
