Re: bracketed paste - chopping trailing newlines

Reordering things a bit for response ...

Hm, standout, boldface, and underline are all used already for different
defaults.  Underline is for isearch, though, so I suppose it's quite
unlikely to clash with paste highlighting.

Another way to approach this would be for a trailing newline to actually
be taken as accept-line, provided that RBUFFER is empty.  This would be
the least different from previous (unbracketed) paste behavior, and
could be independent of the number of trailing newlines.  In contexts
other than PS1, e.g., a here-document, this is identical to keeping
the trailing newline (except that the PS2 prompt is repeated).

Here's a way to try that on for size:

    autoload -Uz bracketed-paste-magic
    zle -N bracketed-paste bracketed-paste-magic
    nl-accept () {
      if [[ "$PASTED" = *$'\n' && -z "$RBUFFER" ]]
        zle -U $'\n'
      return 0
    zstyle :bracketed-paste-magic active-widgets ''
    zstyle :bracketed-paste-magic paste-finish nl-accept
