start editing a new file

Parameters

fnum	file number; if zero use ffname/sfname
ffname	the file name full path if sfname used, any file name if sfname is NULL empty string to re-edit with the same file name (but may be in a different directory) NULL to start an empty buffer
sfname	the short file name (or NULL)
eap	contains the command to be executed after loading the file and forced 'ff' and 'fenc'
newlnum	if > 0: put cursor on this line number (if possible) ECMD_LASTL: use last position in loaded file ECMD_LAST: use last position in all files ECMD_ONE: use first line
flags	ECMD_HIDE: if TRUE don't free the current buffer ECMD_SET_HELP: set b_help flag of (new) buffer before opening file ECMD_OLDBUF: use existing buffer if it exists ECMD_FORCEIT: ! used for Ex command ECMD_ADDBUF: don't edit, just add to buffer list
oldwin	Should be "curwin" when editing a new buffer in the current window, NULL when splitting the window first. When not NULL info of the previous buffer for "oldwin" is stored.
