Subject: Find a capitalised extension's lexer again

Scintillua's detect() matches an extension by its case, and the fallback
e227d1f dropped had lowercased it, so MAIN.C and SETUP.PY lost their
colour. The fake lexer now answers only for the suffixes it knows, as
Scintillua does, which is what lets the check see it.
