I have an alias, called "a".  When executed as "a 1 2" it performs normally.
When executed as "a 1 1", csh leaves my shell hanging in the subsidiary
prompt and a ^D is necessary to escape, leaving a "missing the/endif" complaint.

Here it is:
orphan conor% alias a
if !:^ != !:$ then; echo !:$ ; endif
orphan conor% a 1 2
2
orphan conor% a 1 1
? 
? 
then: then/endif not found.
orphan conor% 

The alias is supposed to echo the second arg if it is different from
the first one.
