Setting `g:ledger_is_hledger` makes it false

[Lense]

Putting let g:ledger_is_hledger = v:true in a vimrc always makes g:ledger_is_hledger end up false. I made a truth/state table while debugging:

g:ledger_bin value	g:ledger_is_hledger in vimrc	g:ledger_is_hledger editing file
'hledger'	unset	1
'hledger'	v:false	0
'hledger'	v:true	0 (!)
'ledger'	unset	0
'ledger'	v:false	0
'ledger'	v:true	0 (!)

Relevant code block:

vim-ledger/autoload/ledger.vim

Lines 35 to 39 in 6d12e23

	if exists('g:ledger_bin') && !exists('g:ledger_is_hledger')
	let g:ledger_is_hledger = g:ledger_bin =~# '.*hledger'
	else
	let g:ledger_is_hledger = 0
	endif

I believe the intended behavior works with this instead:

if !exists('g:ledger_is_hledger')
  if exists('g:ledger_bin')
    let g:ledger_is_hledger = g:ledger_bin =~# '.*hledger'
  else
    let g:ledger_is_hledger = 0
  endif
endif

g:ledger_bin value	g:ledger_is_hledger in vimrc	g:ledger_is_hledger editing file
'hledger'	unset	1
'hledger'	v:false	0
'hledger'	v:true	1
'ledger'	unset	0
'ledger'	v:false	0
'ledger'	v:true	1
