Subject: [PATCH] Fix breaking the 'clean' subcommand caused replacing a
 single-letter variable with the same value in two contexts where it was used
 differently.  That's why you don't use "m" as a variable for hundreds of
 lines in an outer function, and re-use it in closures several times in the
 same function.  Sheesh.
