[PATCH] lib/templates: don't wrap lines that may be code Export this patch

The wrapText function used in the quoted_reply template squeezes
whitespace due to the use of strings.Fields.  As a result any code in
the body would lose leading whitespace for indentation.  There was
already a check to not wrap quoted lines (lines begining with '>').
Add more characters and don't wrap if a line starts with '+', '-',
' ', '\t'.  These characters provide an heuristic that the text is
code or part of a patch.

thanks for the patch.
However I won't merge this, if you don't want wrapping use a different template.

We shouldn't special case characters other than the quoting char.
