starts a symbol (identifier) incremental search forward with the
symbol found near point added to the search string initially.

*** `C-x 8 RET' in Isearch mode reads a character by its Unicode name
and adds it to the search string.
*** By default, prefix arguments do not now terminate Isearch mode.
Set `isearch-allow-prefix' to nil to restore old behavior.
++++
*** More Isearch commands accept prefix arguments, namely
`isearch-printing-char', `isearch-quote-char', `isearch-yank-word',
`isearch-yank-line'.
++++
*** Word search now matches whitespace at the beginning/end
of the search string if it contains leading/trailing whitespace.
In an incremental word search or when using a non-nil LAX argument
*** New command `ses-rename-cell' allows assigning names to SES cells.
** Shell

*** `explicit-bash-args' now always defaults to use --noediting.
During initialization, Emacs no longer expends a process to decide
whether it is safe to use Bash's --noediting option. These days
`file-extended-attributes'. The attributes can be applied to another
file using `set-file-extended-attributes'.
++++
** By default `copy-file' no longer copies file permission bits to an
existing destination; and it sets the file permission bits of a newly
created destination to those of the source, masked by the default file
argument GROUP which causes it check for file group too. This can be
used in place of the 9th element of `file-attributes'.
+---
*** The function `set-visited-file-modtime' now accepts a 0 or -1
argument, with the same interpretation as the returned value of
`visited-file-modtime'.
