Kmail incorrectly breaks into two lines long urls that contain the - character when composing a new mail making the url "wrong"

Example:
Start a new mail and write the long url https://bugs.kde.org/enter_bug.cgi?format=guided&product=kmail&additional_info=OS%3A%20Linux%20%28x86_64%29%20release
It will all be in a single line even if it is longer than the 78 characters length kmail breaks lines. All good so far.

Now try writing http://websvn.kde.org/*checkout*/trunk/l10n-kde4/templates/messages/kdelibs/kdelibs4.pot

Even if it is a much shorter url it will get split in "-" character making the url wrong.

Ideally kmail should detect that i'm writing a url and never split it in new lines

Reproducible: Always
