nhmall ac6e13fd7a allow run-from-removable-device configuration on Windows 
Allow a way to configure NetHack to run entirely from a USB stick
or other removable device in a way that allows everything to
reside entirely on the USB stick, and nothing on the computer's
hard drive. That could be done in versions prior to 3.6.3.

Sample:

i: is a USB stick

i:\nhdist contains the NetHack Windows distribution and a sysconf
file dropped into that distribution with the following entry in it:
	portable_device_top = nethack

No device is included in the portable_device_top entry, the device
is always the device that the nethack exe resides on. If you try
to specify a device in the portable_device_top path, the device
portion will be ignored.

portable_device_top specifies the folder on the device that is writable
by NetHack and as such it cannot be the same folder that the executable
resides in.

i:\nhdist\nethack --showpaths
Variable playground locations:
    [hackdir   ]="i:\nethack\"
    [leveldir  ]="i:\nethack\"
    [savedir   ]="i:\nethack\"
    [bonesdir  ]="i:\nethack\"
    [datadir   ]="i:\nhdist\"
    [scoredir  ]="i:\nethack\"
    [lockdir   ]="i:\nethack\"
    [sysconfdir]="i:\nhdist\"
    [configdir ]="i:\nethack\"
    [troubledir]="i:\nethack\"
NetHack's system configuration file (in sysconfdir):
    "i:\nhdist\sysconf"
The loadable symbols file (in sysconfdir):
    "i:\nhdist\symbols"
Basic data files (in datadir) are collected inside:
    "i:\nhdist\nhdat363"
No end-of-game disclosure file (disabled).
Writable folder for portable device config (sysconf portable_device_top):
    "i:\nethack\"
Your personal configuration file (in configdir):
    "i:\nethack\.nethackrc"

Without that sysconf file in the NetHack distribution folder on the
USB stick with the 'portable_device_top = '  entry, the paths
return to the default locations for 3.6.3 on Windows:

i:\nhdist\nethack --showpaths
Variable playground locations:
    [hackdir   ]="C:\Users\JaneDoe\NetHack\3.6\"
    [leveldir  ]="C:\Users\JaneDoe\AppData\Local\NetHack\3.6\"
    [savedir   ]="C:\Users\JaneDoe\AppData\Local\NetHack\3.6\"
    [bonesdir  ]="C:\ProgramData\NetHack\3.6\"
    [datadir   ]="i:\nhdist\"
    [scoredir  ]="C:\ProgramData\NetHack\3.6\"
    [lockdir   ]="C:\ProgramData\NetHack\3.6\"
    [sysconfdir]="C:\ProgramData\NetHack\3.6\"
    [configdir ]="C:\Users\JaneDoe\NetHack\"
    [troubledir]="C:\Users\JaneDoe\NetHack\3.6\"
NetHack's system configuration file (in sysconfdir):
    "C:\ProgramData\NetHack\3.6\sysconf"
The loadable symbols file (in sysconfdir):
    "C:\ProgramData\NetHack\3.6\symbols"
Basic data files (in datadir) are collected inside:
    "i:\nhdist\nhdat363"
No end-of-game disclosure file (disabled).
Your personal configuration file (in configdir):
