Turning `header` patterns into `signature` patterns in all syntax files was a mistake. The two are different things. In almost all syntax files those patterns are things like shebangs or <?xml ... ?> or <!DOCTYPE html5> i.e. things that: 1. can be (and should be) used for detecting the filetype when there is no `filename` match (and that is actually the purpose of those patterns, so it's a regression that it doesn't work anymore). 2. should only occur in the first line of the file, not in the first 100 lines or so. In other words, the old `header` semantics was exactly what was needed for those filetypes, while the new `signature` semantics makes little sense for them. So replace `signature` back with `header` in most syntax files. Keep `signature` only in C++ and Objective-C syntax files, for which it was actually introduced.
