Actually, the input converter did have some code to expand "~username"
paths. But putting that in the input converter was broken by design;
you don't want the home directory expanded in a path when it's stored
into the database, you want to expand it when the path is used (what
if the user's home dir has moved since you made the DB entry?)
It might be worth pulling that code out of the CVS attic and inventing
a text-to-text "expand_pathname()" function that expands ~username and
perhaps also $ENVIRONMENTVAR in text strings interpreted as pathnames.
But I doubt that having a separate type for filenames is useful.
