SQL language detection breaks if you use a < or > character in an if statement

[jasongisstl]

If you have a less than or greater than character in an if statement, SQL language detection will fail.

E.g:
hljs.highlightAuto("if 5 < 10", ["sql"]);

Returns text with no language highlighting, as "<" is detected as an 'illegal lexeme'.

For Microsoft SQL Server's Transact-SQL (T-SQL), this issue is fixed in #1524

Now works for PostgreSQL (#1804).
As for pure standard SQL, if is not a valid statement anyway.

Sounds like we could close this one then? @egor-rogov

I guess so.
