#12 (load) does not expand paths with tilde

[Chris Rodrigues]

File paths starting with a ~ are not expanded to the user's home
directory in Unix. The filename gets appended to the working
directory instead. For example,

#;> (load "~/scheme/main.scm")
Error in load: error opening
'file:/home/noktakanto/sisc/~/scheme/main.scm'.
