(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.
