Subject: [PATCH] Port r6710 from puzzles: Patch from Ben Hutchings to prevent
 an ugly special case in &splitline in which a line is `split' into a line
 ending in a backslash followed by a completely blank line.

[originally from svn r6714]
[r6710 == fd90d1a7c8224e673361d8b23aadfa01829de77c in puzzles repository]
