Log message (6 lines):
input.c was capable of generating a paragraph structure with no text
in it, if the input paragraph contained (say) an unrecognised
control command and nothing else. Such paragraphs can confuse back
ends later on, so input.c should refrain from generating them. Added
a check and a polite error message (just in case the user manages to
generate an empty paragraph using otherwise legal syntax).
