Only show totals in 'make wc' output

This filter the output of Makefile.latex's "wc" target so that this:

    Words in text: 484
    Words in headers: 15
    Words outside text (captions, etc.): 0
    Number of headers: 9
    Number of floats/tables/figures: 1
    Number of math inlines: 1
    Number of math displayed: 0
    Files: 6
    Subcounts:
      text+headers+captions (#headers/#floats/#inlines/#displayed)
      7+0+0 (0/0/0/0) File(s) total: ./inside-cover.tex
      476+15+0 (9/1/1/0) File(s) total: ./proposal.tex
      1+0+0 (0/0/0/0) File(s) total: ./_proposal-post.tex
      0+0+0 (0/0/0/0) File(s) total: ./_proposal.tex

    (errors:5)

Becomes this:

    Words in text: 484
    Words in headers: 15
    Words outside text (captions, etc.): 0
    Number of headers: 9
    Number of floats/tables/figures: 1
    Number of math inlines: 1
    Number of math displayed: 0
Don't show unused references in "make cite"

This invokes checkcites with the "--undefined" flag, which means that
only undefined citations in the TeX sources will be shown, not unused
references in the bibliography file. This is useful for bibliography
files which are managed by third party applications such as Mendeley, in
with which a single bibliography file can track many hundreds of
academic papers.
Remove compiled binary

Woops!
