I have 'set trimblanks' in .nanorc and yet, most of the time, files get saved with some trailing whitespace remaining.
One could argue that the option is poorly named, but... users should really read the documentation. For trimblanks, `man nanorc` says: "Snip trailing whitespace from the wrapped line _when_ automatic hard-wrapping occurs or _when_ text is justified."
Setting the option really should trim at all times, prior to saving a file.
You can arrange the trimming of all trailing whitespace yourself.
Search for "snipping" in the sample nanorc:
grep -A1 snipping /usr/share/doc/nano/examples/sample.nanorc
That gives:
## For snipping trailing blanks when you save a file:
# bind ^S "{execute}| sed 's/\s\+$//' {enter}{savefile}" main
