quit if one screen when cat short file

[XhstormR]

Is your feature request related to a problem? Please describe.

I'm using lnav as a general-purpose pager. When viewing short files, such as lnav README.md, or cat README.md | lnav, I want it to output the content directly, similar to the --quit-if-one-screen parameter of the less pager.

Describe the solution you'd like

json config item like --quit-if-one-screen parameter of the less pager, to output the content directly if is small file

Additional context
lnav 0.13.2

Previously, the check was hard-coded to dump the file if it was less than 24 lines. I've changed it to check the actual size of the terminal. This mode is only active when the -q flag is passed.

cat README.md | lnav

Note that lnav doesn't recognize Markdown files that are piped in. Currently, it only checks the filename to see if it has a .md extension and then the content will be treated as Markdown.
