Eli Zaretskii cb1e73d1bc Improve accuracy of apropos commands that search doc strings 
It is conceptually wrong for apropos commands that search doc
strings to look for matches of several words only on the same
line, because division of doc strings between lines is
ephemeral.
* lisp/apropos.el (apropos-parse-pattern): Accept an optional
argument MULTILINE-P, and if that is non-nil, produce regexps that
match words in the list even if they are separated by line
boundaries.
(apropos-value, apropos-local-value, apropos-documentation): Use
the new optional argument in apropos commands that search
multiline text, such as doc strings.

* src/search.c (Fposix_looking_at, Fposix_string_match)
(Fposix_search_backward, Fposix_search_forward): Make sure Posix
appears in the doc strings near REGEXP, for better matches.

This directory contains the source files for the C component of GNU Emacs.
Nothing in this directory is needed for using Emacs once it is built
and installed, if the dumped Emacs is copied elsewhere.

See the files ../README and then ../INSTALL for installation instructions.

The file 'Makefile.in' is used as a template by the script
'../configure' to produce 'Makefile'.  This is the file which actually
controls the compilation of Emacs C source files.  All of this should
work transparently; you should only need to change to the parent
directory, run './configure', and then run 'make'.
