Help messages are formatted programmatically with FormatParagraph
in order not to break existing strings in Transifex.

The new format works even if the translation of the strings
modifies the lenght of the message.

Help messages correctly formatted for SVGA text mode (132 chars)

Help messages are formatted programmatically with FormatParagraph
in order not to break existing strings in Transifex.

The new format should work even if the translation of the strings
modifies the lenght of the message.

Fix - syntax error

Correct formatting for 79 chars
