Could anyone familiar with the internals of Jam tell me whether or not there is a maximum line length for an action. The reason I ask is because we have a java compilation action that has a line that just reached 1023 characters (before variable expansion). When we recently modified the action increasing the length of this very long line, Jam would no longer run the action, even if a target was out of date. When we remove our new additions to the long line in the action, the action is run on the out-of-date targets.
