Fix #1 for user which not compiled vim with perl

[stephpy]

• Replaces tabs by spaces
• Fix Error add_ok #1 for user which not compiled vim with perl

I replaced too

 exe ":sign place 4782 name=" . sign . " line=" . line . " file=\".expand(\"%:p\")"

by

exe ":sign place 4782 name=" . sign . " line=" . line . " file=\"".expand("%:p")."\""

I did not test it coz i did not compiled my vim with perl yet, but it seems to be good.

When i'll find time, i'll look at how to implement this for non perl vim ...

[stephpy]

I see, the only one error is than line and file vars are prefixed by <ac>, i'll look at how to delete this char ...

[stephpy]

I just change the position of pos var ... to not retrieve the <ac> char ... Coz i did not find how to delete this char.

Can you test it with perl extension, i would not want to break this bundle when vim is compiled with perl.

I you have any idea to substitute <ac> ...

Thanks for this, looks good! I'll give it a go with and without Perl, and will add the latest on vim.org if everything works.
