Subject: Remove an odd and unnecessary pair of braces.
X-Git-Tag: v8.3.0-rc1~121^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=513382f1b2382a991a9a1866aa81baefd5d91c6c;p=dealii.git

Remove an odd and unnecessary pair of braces.

The whole function's body was enclosed in an extra set of braces. That's
not wrong, but it's at least unnecessary.
