[daip] minpatch

[Eric Greisen]

I did make a fix - someone noticed that the acual minpatch used would
drop every time a small window was cleaned and would not recover its
initial value.  I fixed that coding error.  So your large adverb-set
value is now always used.

IMAGR uses a big patch when it can - minpatch simply forces it never
to use a small one.  I will loook at this error however.  The message
is perplexing...
