	(replace-regexp "^\([ 	]+\|\)
" "")

IOW (in other words): replace all occurrences of strings that consist  
of a series of one or more SPC or of one or more TAB or a mixture  
them or of nothing with nothing.

You can test such regular expressions with isearch-forward-regexp or  
isearch-backward-regexp.

BTW, the linefeed you see in my regexp *is* a linefeed.
