I know you guys are more in the emacs camp but just for reference/inspiration:
in VIM I have a mapping to strip trailing spaces from a file

  noremap <leader>st :%s/\s\+$/<CR>

This could of course go as a sed/grep command in the pre-commit hook. Concerning
the tabs, I have

  " Tabs. Note: Use :retab to clean up mixed indentation
  set expandtab           " Always uses spaces instead of tab characters
  set tabstop=2           " Size of insterted spaces if tab is pressed
  set list                " Highlight tab characters in files
  set listchars=tab:▸\ ,extends:#,nbsp:.,trail:⋅

For the pre-commit hook one could `grep -P '\t' *`. Maybe even better would be
the use of a linter but I am not sure what is most flexible for C code.
