Ability to share names between bfiles and sfiles

[lydia-duncan]

This occurs when specifying a bfile without giving the absolute path (i.e,
relying on the pych installation to move your bfiles and sfiles to its default
search location)

When trying to generate the bfile's function, we get the error message:
... // function name in question
error: control reaches end of function that returns a value
... // Further details and errors

With code in the second block that indicates it is trying to interpret the sfile as a bfile.
At a guess, resolving the name specified does not look at distinct locations, it instead
searches through the known sfile location, then the known bfile location, for the file name.
