Ugh!!!!!

cirdna is using strings for ticklines and intersymbol. That is why the 
value is required.

This needs to be fixed - that part is easy. Simply make cirdna use boolean 
options as it should.

More worrying is that -nointersymbol was allowed. That really must be only 
for booleans.

For example, seqret -nooutfile will write to a file called "N". Not too 
surprising that nobody has tried this before :-)

The boolean testing code is in the right function. Should be easy to modify.
