Bracketed paste: Strip leading spaces if they'd trigger histignore

Browse source 
Similar to the last commit, only for the in-terminal-paste stuff.

Also cleans up the comments on bracketed paste a bit - nobody has
stepped forward to report problems with old emacsen or windows, so
there's no need for a TODO comment.

See #4327.
