Hard line break on empty line in grid table produces invalid latex

[cmadsen]

The following makes latex say ! LaTeX Error: There's no line here to end.

+-----------------------------------+------------------------------------+      
|Total revenue:                     | \                                  |
|                                   | \                                  |
|- Current year                     | 000.000  \                         |

Hard line breaks on empty lines should prepend a \mbox{} when generating latex. Inserting \mbox{} \ by hand works.

I've reduced the failing case to

+------+
| a\   |
|  \   |
+------+

The faulty line in the result is a\\\\ within a longtable environment.

Without the second newline, the LaTeX edition is a\\, which compiles correctly.

+------+
| a\   |
+------+

Without the a the newlines don't appear at all, and we get an empty cell. I suspect the mbox interpretation would be more correct than an empty cell.

+------+
|  \   |
|  \   |
+------+

If it's safe to replace consecutive newlines in tables with \mbox{} or \mbox{} \ I'm happy to implement.

I don't see any issues, so go ahead. But what about the following
alternative? \\[3\baselineskip] for 3 consecutive hard breaks?

That seems a lot nicer and avoids the error. Since this looks and means the same in ordinary paragraph / horizontal mode, I'm wondering if it'd be safe to replace all sequences of LineBreaks within Para etc with these? (Easier to implement, for sure)

I can't see any problem with the suggestion!
