I found inconsistency in misc1.c.

init_homedir() initialises the static variable homedir by checking the
following environment variables:

1. HOME
2. HOMEDRIVE + HOMEPATH
3. USERPROFILE

And vim_getenv("HOME") returns a value with the homedir variable.
However home_replace() uses mch_getenv("HOME") and it doesn't uses
vim_getenv("HOME") nor homedir.

Maybe home_replace() should use homedir instead of mch_getenv("HOME")?
