ref: include pagination info (less/more) in both dag and exp show

[iesahin]

The dvc dag reference has a section about setting the pager something other than less. This information applies to all commands that use pager, and better to be served elsewhere.

Possible candidates:

• How-To (A dedicated page to specify pager for commands.)
• User's Guide

[shcheklein]

Sounds good. Could we though list first what other commands are affected by this?

[iesahin]

Probably only dvc dag and dvc exp show but I'm searching them.

[jorgeorpinel]

If it's just those 2 maybe repeat the pagination paragraph on both for now. Until we have a proper config guide (#340) at least

[iesahin]

dvc exp show also has a --no-pager flag. I'm not sure if takes DVC_PAGER into consideration, I need to test this first.

[iesahin]

It looks dvc exp show takes both --no-pager and DVC_PAGER into consideration.

[jorgeorpinel]

OK so again if it's just those 2 references, let's keep the info in them even if it's slightly repetitive, I think. Sounds like It won't be exactly the same anyway.

[iesahin]

I thought other commands are using the variable, it looks not so. I agree with you to keep them same way.
