418Compile frills: Disable (or enable) emitting bracketed paste mode
419sequences (default enabled). Bracketed paste mode allows programs
420to detect when something is pasted. Since more and more programs
421abuse this, these sequences can be disabled. The command sequences to
422enable and query paste mode will still work, but the actual bracket
423sequences will no longer be emitted. You can also toggle this from the

1574number of 24-bit colours that can be used is limited: an internal 7x7x5 (256
1575colour mode) or 6x6x4 (88 colour mode) colour cube is used to index into the
157624-bit colour space. When indexing collisions happen, the nearest old colour in
1577the cube will be adapted to the new 24-bit RGB colour. That means one cannot
1578use many similar 24-bit colours. It's typically not a problem in common
1579scenarios.
