2aca4e2c02 'main': Make logic more robust. No functional change.
Before this commit, if the value didn't begin with a dollar sign,
_zsh_highlight_main_highlighter__try_expand_parameter() would return 1
by accident.¹  Tweak the input validation to make this behaviour
explicit.  No functional change.

¹ Specifically, it would return 1 because ${parameter_name}'s value
would be the empty string and ${parameter_name_pattern} wouldn't match
that.

5545fb9ab2 'main': In command position, do not highlight directories (unless AUTO_CD is set) and non-executable files.
Fixes #202.

Test expectations are updated.  For example, BUFFER='/bin' is now
highlighted as path_prefix because it's a prefix of '/bin/sh' which
would be valid.  However, BUFFER='/bin;' is now properly highlighted
as an error (unless AUTO_CD is set).

e165f18c75 'main': Fix a bug manifesting under zsh 5.2 and older.
The escaped caret was taken for a negated character class.  This caused test-data/arith1.zsh
to XPass: the arithmetic expansion was consumed by the 'while' loop.

d237a60c9b 'main': Don't highlight arithmetic expansions as command substitutions.
This is not perfect: we don't try to detect cases such as «$((ls); (ls))»,
which look like arithmetic expansions but are in fact command substitutions.

Fixes part of #607.

Introduces #704.

2f4f81cab7 'main': Parameter expansions may not contain assignments.
In «a="b=c"; $a», the '=' sign in the expansion of $a is not active.
