`makeprg` incorrectly set to `(hledger -f g:ledger_main::S print > /dev/null)`

Since #119 vim-ledger incorrectly sets makeprg to (hledger -f g:ledger_main::S print > /dev/null) in Neovim.

The root cause is that the expansion works differently between Vim and Neovim. Also, ::S suffix only works if g:ledger_main is a special wildcard. Was that the intention?

For addressing this issue, we could do one of the following:

1. Roll back Properly escape paths so spaces don't error on load #119, because it's a breaking change.
2. Change to expand(g:ledger_main . '::S') if g:ledger_main being a wildcard is intended. This works in both Vims.
3. Check for Neovim and do 2. for Neovim only.
4. Let users configure the expanded filename by themselves.
5. Ignore, because you don't care about supporting Neovim.

I see exactly this problem with Vim 8.2 - I don't have Neovim installed.

Patch 241a879 fixes it for me.
