please try again with vim-7.1.211 from FC7-updates. I think this was caused by a
comment plugin which has been enabled for some time until I removed it.

I have tested this in FC9, it is still there! However this problem is more major
in this case - Now it actually modifies your *source code* whilst you are
programming.


for example make a new .cpp file and save it.

then re-open it and type

#include <iostream>
#include <cstdlib>

using namespace std;

int main()
{
    const char *wtih = "weak tih";

    cout << wtih << endl;

}


then save. 

This will cause the code to change, where the wtih variable will be renamed to
with! If you are depending on external headers your code wont compile - or even
worse if there is a with and a wtih named variable, then the wrong one will be
referenced if you dont notice the as-you-type substitution.

I've checked the F-7 and F-9 sources and there's no abbreviation for p.e. colour.
The :ab command on a F-9 vim shows 'No abbreviation found'.

Please check your ~/.vimrc, ~/.vim/* and your /etc/vimrc for abbreviations. The
command ':verbose abbreviate' will tell you exactly in which file those
abbreviations have been set.
