5cd1fb26c0 Resolve tilde expansions in command word.

7b4598a764 Highlight arithmetic expansions. 
Fixes zsh-users/zsh-syntax-highlighting#188 in the case that both the
opening '((' and closing '))' have been typed,  The case that only the
opening '((' have been typed is also fixed, but requires a zsh development
build (zsh-5.1.1-52-g4bed2cf or newer); see comments within.

79e8c2dd48 Don't highlight syntax elements as paths. 
Without this, redirections, history expansions, and command separators would
be matched by path_approx.

A test case is simply LBUFFER="<" RBUFFER="" (highlighted as redirection with this
fix and as path_approx without it).

Fixes zsh-users/zsh-syntax-highlighting#204.

for issue #186.

This was broken by c2b9327b07

by the previous commit.

627eb71940 tests: Use $unused_highlight in more places. 
Notably, the 'single-hyphen-option' and 'assign' contexts both default to the
'none' style, so before this patch, the tests would not have detected a failure
to apply those two contexts.

For other contexts, using $unused_highlight only helps detect the case where
the right highlight style (e.g., 'fg=yellow') is used as a result of applying
the wrong context — which should be a theoretical failure mode.

This is part of zsh-users/zsh-syntax-highlighting#198.
