dart analyze cannot analyze file without .dart extension.

I have a script file with the name dgr, and a first line of #! ...path-to-dart-exe. Pretty standard for a Dart script file.

If I try to analyze that as dart analyze ~/bin/dgr, the analyzer reports "No issues", even if the file is full of errors.

It seems the analyzer tries to avoid non-Dart files by ignoring files not ending in .dart, which is reasonable if I'm analyzing entire directories, but when being asked to analyze a single specific file, the analyzer should probably do what is being asked for.

I'm not sure whether this affects other dart sub-commands.
Both dart run and dart format works with no problem.
I don't know if it affects dart fix, haven't been able to make a mistake that fix can fix (probably because the file is not in a context with an analysis options).

It almost certainly impacts dart fix as both tools use the analysis server, which is likely to be where the bug is.
