* .jshintrc: Updated to include more strict options that match
our code conventions.
Also separated into 3 groups:
- stricter (curly, eqeqeq etc.)
- laxer (smarttabs, laxbreak)
- envrionment (browser)
* .jshintignore: Updated to include more third-party/upstream files
that should not be linted.
* Most of it is just routine cleanup, a few notable points:
- jquery.autoEllipsis: Removed unused variable $protectedText.
- jquery.arrowSteps.js: Remove <!-- --> and language="javascript"
that hasn't been needed for almost a decade.
- jquery.byteLimit: Use dashToCamel key for .data(), this already
happens internally in jQuery data(), since data storage should use
keys that are usable as identifiers. The dashed versions are to
populate these from data-attribute-names, which then becomes
data.attributeNames. jQuery data() takes both forms as
convenience.
- jquery.client.js: To avoid a rewrite of it, allowing unexpected
assignments (boss) and eval (evil) in the functions that use that.
Left as it is for now, could use a rewrite later.
- jquery.color.js: Tolerate unexpected assignment for now (boss).
Left as it is for now, should perhaps be refactored later.
Also re-ordered per jshint/jslint to put definition before
invocation. This option can be disabled, but then it doesn't
warn for invoking undefined functions (or typos) at all.
- jquery.expandableField.js: Remove empty switch/case.
- jquery.localize.js: Alias mw global.
- jquery.suggestions.js: Use e.which; jQuery.Event normalizes
e.keyCode etc.
- jquery.tablesorter.js: Alias mw global.
- jquery.textSelection.js: Fix leakage of variable in global scope
of var "i" and "j".
- mediawiki.util.test.js: Fixed implied global `pCustom`.
* Review with -w for your own sanity.
