I have found a bug in vim's recovery.
To reproduce: create a file "test" with 40000 lines, with each line
containing 78 minuses, a la
Copy that file to test_save
Edit test again, add one line, do not do :w, but rather kill vim
Do "vim test" again, press r for recovery, do :wq
The result is that the recovered file test does contain the newly added
line (good), but it misses 292 of the original lines (bad!) I.e.
wc test_save test
40000 40000 3160000 test_save
39707 39709 3136791 test
The above test has been done with vim 7.3 compiled on a 32 bit LINUX machine
and with vim 6.3.82 (from Kubuntu 10.10) on a 64 bit LINUX machine.
Cheers, Bo Milvang-Jensen
Most likely this is solved by patch 7.3.216
Dreams are free, but there's a small charge for alterations.
