* Makefile: added 'ext' to 'all' target
* ext.tex: more changes towards a readable text
* lib4.tex (posix): added set{uid,gid}
* lib2.tex (array): restored doc for typecode and itemsize (which were
there but not visible for dir())
(formerly ../misc/{EXTENDING,REFCNT,EMBEDDING}). Also affects Makefile.
* text2latex.py: script to do part of the conversion from an plain ASCI
text file (in my particular style) to LaTeX.
(Chapter/section/subsection headers, and verbatim sections.)
* partparse.py, texipre.dat, fix.el, Makefile: Minor cleanup of latex ->
info conversion process (at least it works again, and with less
debugging output). Removed fix.sh.
* lib1.tex (section{Built-in Functions}): adapt description of str() and
repr() to new situation.
* lib3.tex (Module os): added exec*() variants.
* lib3.tex (Module posix): added execve().
* lib2.tex (Module array): documented reality; remove typecode and
itemsize, add byteswap, rename read/write to fromfile/tofile, and
re-alphabetized.
* lib1.tex (Built-in Functions): renamed bagof() to filter().
