Silence warning from modern perl about unescaped braces

Back-patch commit 76a1c97bf21c301f61bb41345e0cdd0d365b2086 into
the older branches (9.5 and before).  This is needed because perl
5.26 and later treats the case as an error not just a warning.

Original patch by Andrew Dunstan, need for back-patch noted by
Ashutosh Sharma
