RFC: Highlight warnings (valid syntax that might not do what its author intended)?

[danielshahaf]

Consider:

% cd ~/src/zsh
% print -l Test/V<1-2>*

That command prints:

V01zmodload.ztst
V02zregexparse.ztst
V10private.ztst
V11db_gdbm.ztst
V12zparseopts.ztst
V13zformat.ztst

This behaviour is correct, but might not be what the user intended.

Would it be useful to highlight such things as warnings?

(To clarify, I'm only asking about the user-visible functionality. How to implement it is a different kettle of fish.)

Possible uses:

• Empty commands: foo; ; (currently, unknown-token)
• Semicolons in array assignments: foo=( bar ; baz ) (see 3ca93f8 (updated in 81267ca))
• Numeric glob adjacent to something that might match a digit: Test/V<1-2>*
