Well, id:1405026779-29966-1-git-send-email-tomi.ollila at iki.fi (*) had -nw
parsing, but I can live without...

But more than that one important feature has to be agreed before initial
interface is locked down -- how to provide body content from command line
without resorting to temporary files. In (*) --body was adding those lines
instead of reading file and I later suggested that --include or --insert
could do the same as -i ... but I am open to any solution that gives me
opportunity to provide body *content* from command line.
