Aliased commands may break geometry

[desyncr]

As per #59. Aliased commands may break/change geometry inner workings.

Avoid this with a similar approach to zsh-users/zsh-syntax-highlighting#390:

At the top:

# Save aliases into a variable and remove/unalias everything
zsh_highlight__aliases=`alias -L`
builtin unalias -m '*'

At the bottom:

# Restore aliases & kill global variable
eval "$zsh_highlight__aliases"
builtin unset zsh_highlight__aliases

[frm]

As I mentioned in #59 looking through the code there don't seem to be many instances of possible aliased commands.

A possible solution would be prepending with command rm or \rm, even though that makes the code messy.

Unaliasing and aliasing over and over is going to affect render time, isn't it?

[desyncr]

I guess this issue was left hanging out since this issue was resolved with \rm.
