Hi,
this patch addresses the following bug:
When 'smartcase' is set and using CTRL-L to add to the search
pattern it may result in no matches. Convert chars to lower case?
(Erik Wognsen, 2009 Apr 16)
The description is taken from
http://code.google.com/p/vim/source/browse/runtime/doc/todo.txt?r=63157185aea525b39b1238df3ffbf4ec0fea10b1#482
and the original mail thread describing the problem is
http://groups.google.com/group/vim_use/browse_thread/thread/7321c95ebde237e3/2cd4e07431dcaf3c
The patch does what the description suggests, i.e. the added character
is converted to lowercase if 'ignorecase' and 'smartcase' are set and
CTRL-L is pressed during an incremental search.
