Agreed.

In other words, this would let us pipe with style.  :-D

In addition, "set style enabled" could be made an auto-boolean
setting, with default "auto", enable styling iff outputting to
a terminal.  Then, "on" would force styling even if outputting
to a pipe.  This would let you force styling with:

 (gdb) with style enabled on -- | apropos -v breakpoint | less
