bug#28124: 24.5; fundamental-mode has electric-indent-mode on by default

[Matthias Meixner]

Hello!

 

Fundamental-mode has electric-indent-mode on by default. As a result when pressing return leading whitespace is removed which is highly unexpected in fundamental-mode.

 

Example:

 

Buffer has:

1:                                 abc

 

Cursor is at start of line and pressing enter results in

 

1:

2:abc

 

Instead of

 

1:

2:                                 abc

 

This is highly unexpected and makes it hard to edit files that have some hand crafted indentation (e.g. ASCII graphics). Trying to insert empty lines destroys the hand crafted indentation. This is not expected when using fundamental-mode and I consider this as a serious bug, since it essentially renders fundamental-mode useless. Globally disabling electric-indent-mode is not an option, since that would also disable it for other modes, where it should be available (e.g. C/C++ mode).

 

Regards,

 

Matthias Meixner
