When displaying messages (i.e. not in the composer), KMail allows to choose between monospaced and variable-width fonts.  Unfortunately, often the latter is more readable, while the former is better for ASCII art (AA).  Since AA is common in .signatures, it would be cool if there was an option to have signatures (separated by "--") be always displayed with monospaced fonts.

At the same time, it does not make much sense to have quotations in signatures highlighted.  The disadvantage of that is that the quotation regexp matches AA very often (e.g. when a line starts with / or |).  That should be prevented IMO, without the need for a configurable option.
