IIUC, getpwuid() is Unix-specific; the equivalent on Windows would not
exist or be very different, wouldn't it? (not that I know what it would
be; $HOMEDRIVE$HOMEPATH maybe, i.e., in Windows notation,
%HOMEDRIVE%%HOMEPATH%). So if such a solution were to be implemented, I
guess that (considering ":help design-multi-platform") there would have
to be in some source file something similar (but probably not identical) to:
[set homepath to $HOME]
if ( homepath == '' )
homepath = getpwuid().login_dir
But if $HOME is unset on Unix, wouldn't there be a lot of other things
which would fail? And if there would, wouldn't it be a better solution
to solve the problem across the board (by keeping $HOME defined in some
sensible manner) rather than for one software package (Vim)?
