Whitespace cleanup.
Fixup zshrc/sourcme to retain $TERM that we start with.

Some /etc/profiles seem to have TERM=xterm-color set unconditionally.

So we save the value in ORIG_TERM and if running under ssh send eterm-color sequences.

All this rigamarole for making term-mode and ssh'ing under it to work sanely. /sigh so many hacks.
