Not positive on the "correct" interpretation of ~ in bash; but in
cygwin's bash, ~ is only defined on startup -- changing HOME after that
will not change the value of ~. In fact, to get it right, you'll need to
set HOME the way you want it before starting bash. I do this with an
icon and a batch file:
- icon runs "c:\bin\shlogin.cmd /home/dumser"
- shlogin.cmd contains
    @echo off

    set HOME=%1
    if     "%2"=="" c:\bin\sh -login
    if not "%2"=="" c:\bin\sh -login -c "%2 %3 %4 %5 %6 %7 %8 %9"

(I tried using %* [CMD's equivalent of $*] after shifting %1 off the
stack but that didn't work -- the first argument did not get dropped off
%*. Does anyone know of a way to do this without having to manually
expand %2 %3 ...?)

Of course, Win95's COMMAND.COM is less featured than even CMD so you'll
probably need to use the brute force method above.
