Comment #6 on issue 287 by [email protected]: Newline substitution
behaviour
https://code.google.com/p/vim/issues/detail?id=287
I've noticed another strange behaviour of previous code, that is also fixed
by my patch:
Previously (in the bugged code since 7.4.232), the single-line
case ':s/\n//' was a no-op for what regards text changes. But it wasn't a
complete no-op, as it still modified the last-change position, and reported
1 substitution in 1 line. In other words, it introduced an "empty" change,
that was visible with the :changes command, and undoable through undo.
After my patch, single-line case isn't no-op anymore, except in the very
last line.
But in that case, our approach behaves correctly, resulting in a complete
no-op. This is, no change is recorded, nor listed, nor undoable, which
seems the correct thing to do.
Now, I don't know how vim pre-7.4.232 behaved regarding that.
bangpath, could you please check that case?
Was an empty change recorded before? How many substitutions/lines were
reported?
Thanks.
