thanks, master works for me again

i use this a lot when programming as it's a quick method to get to the start of the line where the code lives :)

The attached patch (against git c8363a0) should fix it.

The problem is do_home() optimizes a bit too much in the case of a smart home. In every case where we could have moved to a different chunk, placewewant is set to zero. However, if we do a smart home, that's the one exception: placewewant should be set to the column where the indent ends. The patch makes nano use xplustabs(), which sets placewewant to the proper column in all of these cases.

(file #41813)

after commit 9f2c80db24d96b46283387c49030edbf744f7828 (moving: when determining where we are on the screen, use placewewant), smarthome no longer works correctly

to reproduce:
- printf '\t%s\n' a b c > file
- run `nano -I -A file`
- hit <home> to move cursor to "a"
- hit <down arrow> to move cursor down a line

before that commit, the cursor would move to "b". after that commit, the cursor is incorrectly reset to col 0.
