That was the good news. Now the bad news - two bug reports.

Firstly if you clear the workflow parameter (leaving it empty), then
the caption is used for the highlighted placeholders BUT only the
first word is used, e.g.

${Minimum read length (after any clipping)}

Initially the the placeholders show "Minimum read length (after any
clipping)", and if you enter a value like "30" then "30" is shown. If
you then edit the field to become empty, the placeholder now
shows just "Minimum".

Furthermore, if I leave my workflow parameters empty, and
press execute, I get a traceback ending with:

AttributeError: 'WorkflowStep' object has no attribute 'module'

Since an empty value is valid for some tools for some parameters
(e.g. optional text fields) I would have expected any error later -
from the tools themselves if they don't like the empty value.
