highligting tabs and trailing spaces

Add the following to .vimrc:

highlight SpecialKey ctermfg=DarkGray
set listchars=tab:»-,trail:~
set list

That makes something like that:

map <silent> <F7> :exec ":e ".(expand("%") =~ ".h$"
       \       ? glob(substitute(expand("%"), ".h$", ".cpp", ""))
       \       : substitute(expand("%"), "\\.cpp$", ".h", ""));<CR>

to be displayed that way:

map <silent> <F7> :exec ":e ".(expand("%") =~ ".h$"~
»-------\»------? glob(substitute(expand("%"), ".h$", ".cpp", ""))
»-------\»------: substitute(expand("%"), "\\.cpp$", ".h", ""))<CR>

Tabs are now plainly visible and also public enemy trailing space on first line became apparent.

P.S. Nice character '»' requires set encoding=utf-8. That looks great with "Andale Mono" and "Black Bold" color set in PuTTY to (39,39,39).
