[Message part 1 (text/plain, inline)]

Severity: minor
Tags: patch

First off, thank you very much Protesilae for the new translation of the
tutorial!

While reading it I noticed a technical discrepancy with other tutorials:

0. emacs -Q
1. C-u C-h t Greek RET

If the Emacs frame is short enough, I see:

[short.png (image/png, attachment)]

[Message part 3 (text/plain, inline)]

And if it's tall enough, I see:

[tall.png (image/png, attachment)]

[Message part 5 (text/plain, inline)]

IOW, the multiline Greek translation of:

  [Middle of page left blank for didactic purposes.   Text continues below]

is either half-erased in short frames, or divided by several blank lines
in tall frames.

One solution would be to limit the Greek translation to a single line as
in other translations, but why not instead teach tutorial.el to handle
multiline instances of this comment, as in the following patch?

Subject: [PATCH] Support multiline [...] comments in Emacs Tutorial

* lisp/tutorial.el (help-with-tutorial): Don't assume [...] comment
spans a single line; instead skip it as a sexp.
