I have read in http://forum.wordreference.com/threads/would-never-or-would-entirely-avoid.3250069/#post-16454853 that we use would for The regular habit/practice. The website says as follows:
Would is also used to indicate a habit A: "Look what you have written here, "If you want to see mountains and beautiful valleys, go to nepal." B: "What is wrong with that?" A: "I would never write "Nepal" without a capital letter." -> Here the would indicates a habit or regular practice. " My/The regular practice is never to write "Nepal" without a capital letter."
Do we really use would to mean The regular practice/habit( Which started in past and continues to present ? If yes, why this use and meaning of "would" hasn't been listed in any grammar books or dictionaries ?
I have checked even in http://dictionary.cambridge.org/grammar/british-grammar/would But couldn't find it.
