Why doesn't M-x grep check that it has been given at least two
parameters, else it is bound to fail, as
$ grep
$ grep pattern
won't get far without some file arguments.
Yes
$ grep pattern pattern #wrong
will still pass as that would look the same as
$ grep pattern file
etc. but the check would be better than nothing.

Why two? For example, for "git-grep pattern" just one is enough.

$ emacs
(grep "grep -nH -e love")
Will always fail. And the user will think "well, I can't find the love
letter she sent me, and thus can't find her address, so I will just give
up," when all along he just forgot to give the filename.
Whereas normally
$ grep love
would hang, waiting for input, so he would know that the relationship
still had a chance, and it was just emacs that was the reason the two
would have lost touch...

If you tend to forget the pattern or file argument there is a reliable grep
known as `M-x rgrep' that asks you what and where to search.

Yes, I use that too.
And that is what is causing me to even remember less that M-x grep needs
more arguments when I use it !

Then customize `grep-command' to something like "grep -nH -e pattern *"
that would remind you to replace the default search string "pattern"
and to replace "*" with actual file names to search.
