Hm, not a bad option.  My concerns are that you will have to write a
lot of "\."'s for the extension delimiters and "\'"'s for matching
their ends.  And if you fail to do that correctly, mismatches will
happen which would be rather fatal when it comes to deleting files.

In any case I am thinking about optionally opening a window which
displays the files to be deleted so that the user can check if there
is anything she wants to keep.

Additionally (not so much related to the above) I changed `TeX-clean'
in a way that it will delete intermediate files if being called
without argument and both intermediate and output files if being
called with a prefix argument.  Consequently, in `TeX-command-list'
there will be both a "Clean" and a "Clean All" entry.

But this will only work for very simple regexps without grouping.

ELISP> (custom-split-regexp-maybe "\\.\\(foo\\|bar\\)")
("\\.\\(foo" "bar\\)")
