directory-abbrev-alist

[Alexander Klimov]

There is a little inconsistency in documentation of
directory-abbrev-alist: comments in code proposes to start each
`from' string with \`, while files.texi proposes ^ (the same,
except in file names with newline). The initial value proposed
by defcustom should reflect this convention. The following patch
fixes both problems:
