Thanks Martin.
I will investigate this. The patch passed the regression test, but this
issue may have been hidden by wdiff.
My current answer is that in order to have a \ displayed in the man page,
a \\, \e or \E has to be used. \\ is changed to \e previously in
shiftline, and thus a line ending by a \ indicates an input line
continuation.
I need to test this with specific man pages.
I will also try to pass the regression test with diff instead of wdiff with and
without this patch.
Note: This patch only corrected 2 pages.
