Subject: [PATCH] Added a user-friendly error message when processing bad
 :treat_as

When the indentation after :treat_as mappings is wrong, we may get a symbol as ctype.
The error signaled by gtype.gsub is not userfriendly, so instead, we test for symbols
and issue a user friend error message in that case.
