  Log Message:
  -----------
  Fix bugs when an included file name is typo corrected.

D52774 fixed a bug with typo correction of includes, but didn't add
a test.

D65907 then broke recovery of typo correction of includes again,
because it extracted the code that writes to Filename to a separate
function that took the parameter not by reference.

Fix that, and also don't repeat the slash normalization computation
and fix both lookup and regular file name after recovery.
