Command: more - displaying files

Description:
	Lets you display files - step by step for longer files. You
	get the first lines of the file and you are prompted something
	like "More /text/init_text (line 23):".

	You have following commands in 'more':
	'help', 'h', '?': shows a few help lines,
	'q'             : quits "more" - leaving to normal command mode,
	'!<command>'    : escapes to the normal command mode - see below,
	'u'             : shows previous page - going up,
	'', 'd'         : shows next page - press <ENTER> (or 'd<ENTER>',
	<number>        : shows page starting with line <number>,
	<anything else> : shows the current page again.

	'!' is interpreted as an escape to the normal command mode that
	is to say you leave the "more" mode just for this one command
	(e.g. 'look', entering '!look') and your next input will be in
	"more" mode again.

Syntax:
	more <filename>

Examples:
	more /text/init_text
	more ../master.c
	more ~/master.c
	more ~scumbag/master.c

Note:
	Since September 15th 2017 'more' makes use of MORE_OBJ, that
	is also used with 'help', on bulletin boards etc. See 'man
	lib/more'.

	A possibility to change the amount of lines shown in one go is
	planned - something like 'set lines 40'.

	The word "more" derives from the command 'more' on Unix-like
	systems for skimming/paging files.
