A REPL's language is named and found as the syntax table finds one: aliases, any case

Repl took only the grammar's exact name, and a file's language was found by a case-sensitive suffix of its path, apart from the aliases a code fence already had. The aliases move to grammar_manifest with byName and byPath, which syntax, Repl and langOf share, so `Repl py` and a .PY file work. The line-by-line warning is for the python language, not an id that starts with python. Joincol's doc line was sitting on Repl.
