Default value for `concealcursor` documentation incorrect

[paulkre]

The README states that this plugin uses the value "inc" for the concealcursor setting by default:

https://github.com/Yggdroot/indentLine/blob/7753505f3c500ec88d11e9373d05250f49c1d900/README.md?plain=1#L77-L82

But that would mean that on the line the cursor is on, all "conceal effects" would be removed, right? This is not the case when I use the plugin. I have to set concealcursor-=inc manually and then I have also have to set let g:indentLine_setConceal = 0 to make it work.

I understand why "inc" is not actually the default but this should be documented correctly to avoid confusion.

Also, changing the value for indentLine_concealcursor does not seem to be working at all.
