Suspected Validator bugs & cleanup

[nyurik]

These were found as I was porting validator "auto-fixes" to the new tool -
​https://wiki.openstreetmap.org/wiki/Quick_fixes#JOSM_autofixes , mostly for demo & discussion purposes. Some might actually be ok, but documenting here to be safe.

• /footway:/ should be

  /^footway:/
  

• /^(...)/ instead of

  /^(...)$/
  

• /\+.*/ ->

  /^\+\d/
  

• /.../ ->

  /^(...)$/
  

• Several tests use ["aaa"=*"bbb"] syntax, but the =* is not documented in MapCSS or in MapCSSImplementation

• /footway:/ should be

  /^footway:/
  

OK

• /^(...)/ instead of

  /^(...)$/
  

This is to include the highway types with _link extension too. However we could add them explicit.

• /\+.*/ ->

  /^\+\d/
  

OK

• /.../ ->

  /^(...)$/
  

OK with ^, but $ has the same _link problem

• Several tests use ["aaa"=*"bbb"] syntax, but the =* is not documented in MapCSS or in MapCSSImplementation

It is documentet at MapCSSImplementation, search for [key1 = *key2] on this page.
