I am writing Perl scripts using vim. I really love this software, and when I
find this bug, I really want it to be fixed right away.
The situation is:
platform: Ubuntu 12.04 LTS, terminal
case:
I split the screen into 3 parts used ":vs" under command mode, and each part of
it was editing a Perl script file. Then in one part of it, I did this ->
Esc
:edit some_directory
And then comes the bug: the authority of the file being opened in one other
part of the screen was changed into 'Readonly', and number of lines
disappeared, too.
content of my vimrc file is added below, hope somebody can help me with this,
thank you!
