Don't store docstrings of preloaded .el files in etc/DOC

2021-12-31T04:17:45+00:00

Since the location of those files changes between build time and
installation time, this requires to tweak the file name used in those
(#$ . NNN) references during the dump so they don't hardcode the build
directory.  We do it in the same way as was already done for those
same file names in `load-history`, except we convert them back to
absolute file names more lazily (i.e. when fetching the actual
docstring rather than at startup), which requires remembering the
`lisp-dir` computed at startup in the new `lisp-directory` variable.

* src/Makefile.in ($(etc)/DOC): Don't scan Lisp files any more.

* src/lread.c (Fload): Use relative file names for `load-file-name`
when preloading for the dump, like we already did for `current-load-list`.
(read_list): Don't zero-out dynamic docstring references during the
preload since they won't be filled later by Snarf-documentation any more.
(read1): Remove the hash-hack for doc references that were zeroed.

* lisp/startup.el (lisp-directory): New variable.
(command-line): Set it.

* src/doc.c (get_doc_string): Use `lisp-directory` for dynamic
docstring references using relative file names.
(syms_of_doc): Add `Qlisp_directory`.

* lib-src/make-docfile.c (scan_file): Don't handle `.el` or `.elc`
files any more.
(IS_SLASH): Remove macro, not used any more.
(skip_white, read_lisp_symbol, search_lisp_doc_at_eol)
(scan_lisp_file): Remove functions, not used any more.

* doc/lispref/loading.texi (Library Search): Mention `lisp-directory`.

Prefer $(info) to @echo

Have GNU Make output some diagnostics directly, instead of forking
and execing a shell to do it.
* GNUmakefile (help):
* doc/lispref/two-volume.make (vol2.pdf, elisp2med-init)
(elisp2-init):
* doc/misc/Makefile.in (echo-info, echo-sources):
* lib-src/Makefile.in (archlibdir, install, check):
* src/verbose.mk.in (AM_V_AR, AM_V_CC, AM_V_CXX, AM_V_CCLD)
(AM_V_CXXLD, AM_V_ELC, AM_V_ELN, AM_V_GEN, AM_V_GLOBALS)
(AM_V_RC):
* test/Makefile.in (subdirs, subdir-targets):
Prefer $(info) to @echo.
* GNUmakefile (MAKECMDGOALS, configure, Makefile):
Prefer $(warning) to @echo >&2.
* src/verbose.mk.in (AM_V_ELN): Output target, like the others.
