3.1b1: The consumption of whitespace inside braces has changed weirdly since 3.0 #6564
Description
Tried using tagged release 3.1b1 as well as current master (1101cff) built from source on Fedora 30, running in Gnome Terminal.
I just noticed this while responding to #5880.
In 3.0, extra whitespace inside of braces was consumed from both sides:
$ echo .{ foo bar }.
.foo bar.In 3.1b1, (perhaps due to the changes from #5869?) we trim whitespace but only from the front:
$ echo .{ foo bar }.
.{foo bar }.Honestly, I'm not sure what should be happening. Do we want to preserve everything inside of braces that don't contain a comma/variable? Or, do we still trim spaces from the front and back like we do when there is a comma/variable? Consider that
$ echo .{ foo , bar }.
.foo. .bar.still comes out symmetric in 3.1b1.
