" This is an updated, more powerful, version of the function discussed here:
" http://www.reddit.com/r/vim/comments/1rzvsm/do_any_of_you_redirect_results_of_i_to_the/

" The purpose of this function is to make the results of ']I', '[I', ']D', '[D', ':ilist' and ':dlist'
" easier to navigate and more persistant by using the quickfix window instead of the default list-like interface.

I updated the function as per @johnmastro's comment above and @Kyiv's comment on reddit:

• better check for the existence of a:1,
• better check for filename lines

New version jumps to the actual match not the the line as it did (stupidly) before.

Line 47, for my use case, should be:

let filename=split(line, '\.\./')[-1]

I have includes like this in *.hpp file:

#include "../foo/bar.hpp"

Snippet shows such paths as:

~/path/to/../foo/bar.hpp

And hitting Enter on top of such item opens empty buffer with path like in quickfix. Going to netrw opens correct folder, and hitting Enter opens file in correct form foo/bar.hpp.
[count][<c-i> also works well for such case.

Fixed the column jumping.

Modified line 47 as per c0ffeeartc's comment. Didn't notice any undesirable side effect.

I'm wondering if I should turn this thing into an actual plugin. On one hand it would help tracking issues, on the other hand this function may be too small for that.
