[docs] [issue23174] shelve.open fails with error "anydbm.error: db type could not be determined"

[Anand Reddy Pandikunta]

Anand Reddy Pandikunta added the comment:

dbm.whichdb mentions that it returns empty string ('') if the file’s format can’t be guessed. Enhancing exception message should suffice.
