Re: [code] Feature request: snippet._insert should allow replacing the selection

I just wanted to add, that this not only happens when the whole line is
It happens to me even on single words. Point is, that it's not happening
all the time, only sometimes. Which makes it very difficult to recreate.
I noticed that it happened to me when I used line wrapping / folding. I
will try without code folding in the next few days to see whether I am
Furthermore I can imagine trouble with code folding, difference between
selecting text with mouse and keyboard, multiple snippets within a single
line (code folding), multiple snippets in a specific time or order (kind of
a buffer problem)...

I really hope that we can locate and eliminate this "bug". It's really
annoying to notice in the output that there is a duplicate text.

Cheers, Sebastian
