It's not that you don't know TECO; it's that you don't know EMACS argument
conventions.  Your point is that there is no standard way to force a function
bound to a key to take a string argument it would normally check for if
invoked via M-X.  X-D (M-X Dired), for instance, will ask for a string arg if
given a ^U arg.  M-X Read Mail has no such feature.

That's a general problem, and not a problem in documentation.  The standard
way to find out about arguments in EMACS is to look at the manual in the info
hierarchy, or to look at the printed manual.  There is no M-X Documentation
Apropos, although with suitable keywords placed in the manual, one could
write it.  Any takers?
