directory-abbrev-alist

[Alexander Klimov]

There is a little inconsistency in documentation of
directory-abbrev-alist: comments in code proposes to start each

except in file names with newline). The initial value proposed
by defcustom should reflect this convention. The following patch
fixes both problems:
