* replace.el (occur-accumulate-lines): Add optional arg `pt'.
(occur-engine): Add local variables `ret', `prev-after-lines',
`prev-lines'. Use more arguments for `occur-context-lines'.
Set first elem of its returned list to `data', and the second elem
to `prev-after-lines'. Don't print the separator line.
In the end, print remaining context after-lines.
(occur-context-lines): Add new arguments `begpt', `endpt',
`lines', `prev-lines', `prev-after-lines'. Rewrite to combine
after-lines of the previous match with before-lines of the
current match and not overlap them. Return a list with two
values: the output line and the list of context after-lines.
* search.texi (Other Repeating Search): Remove line that `occur'
can not handle multiline matches.
* occur-testsuite.el (occur-tests): Add tests for context lines.

* replace.el (occur): Doc fix.
(occur-engine): Set `begpt' to the beginning of the first line.
Set `endpt' to the end of the last match line. At first, count
line numbers between `origpt' and `begpt'. Split out code from
`out-line' variable to new let-bindings `match-prefix' and
`match-str'. In `out-line' add non-numeric prefix to all
non-first lines of multi-line matches. Finally, count lines
between `begpt' and `endpt' and add to `lines'.
Use `occur-engine-line' instead of duplicate code.
(occur-engine-line): New function created from duplicate code
in `occur-accumulate-lines' and `occur-engine'.

* replace.el (occur-1): Don't display regexp if it is longer
than window-width. Use `query-replace-descr' to display regexp.
(occur-engine): Don't display regexp in the buffer header for
multi-buffer occur. Display a separate header line with total
match count and regexp for multi-buffer occur.
Use `query-replace-descr' to display regexp.
* replace.el (query-replace-history): Give it a doc string.
(map-query-replace-regexp): Use query-replace-from-history-variable
and query-replace-to-history-variable.
For def=recenter, replace `recenter' with `recenter-top-bottom'
that is called with `this-command' and `last-command' let-bound
to `recenter-top-bottom'. When the last `def' was not `recenter',
set `recenter-last-op' to nil. (Bug#4981)
(perform-replace): Add processing of new multi-buffer keys bound
to `automatic-all' and `exit-current'. Set `query-flag' to nil
if last input char was `automatic-all'. Set new local variable
`multi-buffer' to t when one of new two keys were typed. Return
non-nil value of `multi-buffer' that tells to calling functions
to continue replacement on the next file.
(keep-lines-read-args, occur-read-primary-args):
Call `read-regexp' instead of code moved to new function.
(keep-lines, flush-lines, how-many): Remove parenthesis and colon
from the end of prompt.
(replace-re-search-function): Doc fix.
regexp-history and display it in the prompt, but don't add to the
list of minibuffer defaults. Bind history-add-new-input to nil to
not add automatically `default'. For empty input return `default'.
Otherwise, add `input' to regexp-history and return it.
(occur-1): Signal an error for the empty regexp.
be used to reveal or highlight the location of a match.
(occur-mode-goto-occurrence)
(occur-mode-goto-occurrence-other-window)
(occur-mode-display-occurrence): Run
`occur-mode-find-occurrence-hook'.
Check search-upper-case before calling isearch-no-upper-case-p
to set case-fold-search.
(occur): Doc fix.
(occur-1, perform-replace): Check search-upper-case before calling
isearch-no-upper-case-p to set case-fold-search.
