Small bug in org store link.  To reproduce, put the cursor on line 1007 
and run org-store-link.  Then use the result to create a hyperlink in an 
org file, which for me looks like:

    
[[file:~/lib/c/pkgs/quicknet/qnstrn.cc::ftr1_window_offset%20ftr1_window_len][call]]

Then click on that hyperlink.  I get sent to line 899 instead of line 
1007. 

It looks like the reason is that org tosses out puncutation (+>,).  I've 
found that, when linking to source code, punctuation is a big deal, so, 
if possible, it would be nice if org mode was made sensitive to it.

Keep up the good work,

Scott
