| === UnwrapText |
| |
| Remove (best effort to) the hardcoded wrapping from a message. |
| |
| If the text is "format=flowed" then deflows the text. Otherwise it forces a dewrap of the text. |
| |
| |
| Parameters: |
| |
| * quotewidth - when we try to dewrap e quoted text it helps knowing the original |
| with, so we can reconstruct "wrapped wraps" created by multiple wrappings by clients with |
| different original width or simply to the add of the heading ">" that increase the line |
| length. |
| |
| The value should be "WIDTH+X" if the original length is known, "-X" otherwise. |
| |
| In the latter case the length of the longer line will be used. |
| |
| X is the tollerance needed for the quoting chars: if the original width is known the suggested |
| value for X is 2 (because of "> " prefix), otherwise it is suggested to increase it to a value |
| like 10 (-10) |
| |
| In summary, if the original wrap is known (for example 76, for flowed messages) *quotewidth = 78* |
| |
| Otherwise *quotewidth = -10* |
