load line number of the tag in the tagsfile

As per the documentation of ctags (http://ctags.sourceforge.net/ctags.html), we need to specify ctags fields +n to get the line number of the tags. This help with better navigation with use of ctags. Without this change, the line number of the tags fetched was coming out to be 0 for all tags. Tested that with this diff, the tag navigation works as expected.

Sounds reasonable. I wonder why it worked for me without the -n option?
