Hi there-

   Please pardon the dumb question if this has been covered before.  I did some brief searches of the archive and couldn't find it...

   I'm running plan9port on macOS.  I noticed that in acme, (and also sam) if I select part of a string and press delete, the selection gets deleted and also one additional character in front of the selection.  For example, if I type "/path/to/file" and double-click file, file gets highlighted, and if I press delete, "/file" gets deleted leaving me with "path/to".  This seems counter-intuitive as I expected only what I had highlighted to be deleted.

   There is a GitHub issue (#424) https://github.com/9fans/plan9port/issues/424 filed for this as well.  

   Just curious, is this by design, or is this a bug?  I'm inclined to think it's by design as it occurs within sam as well.

   As always, thanks!!
