Использование в приложениях (Application usage)
When the standard output is not a terminal, only the -s filter-
modification option is effective. This is based on historical
practice. For example, a typical implementation of man pipes its
output through more -s to squeeze excess white space for terminal
users. When man is piped to lp, however, it is undesirable for
this squeezing to happen.
