I've found that in order to improve the look of my TeX documents, I use
ties (tildes) quite heavily, to join words inseparably together.

Is there any agreed-upon convention, in the typesetting world, for when 
two words should not be separated by a line break?

I've developed the following rules of thumb:

	1. A one-letter or two-letter word which begins a sentence,
	   or which follows a comma or other punctuation symbol within
	   a sentence, should be tied to the next word. 

	   The same is true for one-symbol or two-symbol mathematical
	   expressions (e.g. $a$ or $a\cdot b$), although of course
	   it isn't good style for them to appear at the beginning
	   of a sentence.

	2. A one-letter or two-letter word which ends a sentence
	   should be tied to the preceding word.

	   The same is true for one-symbol or two-symbol mathematical
	   expression.  (It's OK for them to appear at the end of 
	   a sentence.)

These rules seem pretty good to me, but does anyone have a longer set?
