* job.c (construct_command_argv_internal): Sanitize handling of
backslash/newline pairs according to POSIX: that is, keep the
backslash-newline in the command script, but remove a following
TAB character, if present. In the fast path, make sure that the
behavior matches what the shell would do both inside and outside
of quotes. In the slow path, quote the backslash and put a
literal newline in the string.
Fixes Savannah bug #1332.
* doc/make.texi (Execution): Document the new behavior and give
some examples.
* NEWS: Make a note of the new behavior.
* make.h [WINDOWS32]: #include <direct.h>.

* read.c (find_char_unquote): Accept a new argument IGNOREVARS.
If it's set, then don't stop on STOPCHARs or BLANKs if they're
inside a variable reference. Make this function static as it's
only used here.
(eval): Call find_char_unquote() with IGNOREVARS set when we're
parsing an unexpanded line looking for semicolons.
Fixes Savannah bug #1454.
* misc.c (remove_comments): Move this to read.c and make it static
as it's only used there. Call find_char_unquote() with new arg.
* make.h: Remove prototypes for find_char_unquote() and
remove_comments() since they're static now.
Implement the MAKE_RESTARTS variable, and disable -B if it's >0.

* NEWS: Mention MAKE_RESTARTS.
* main.c (main): If we see MAKE_RESTARTS in the environment, unset
its export flag and obtain its value. When we need to re-exec,
increment the value and add it into the environment.

one instead.

always_make_set is set AND the restarts flag is 0. When building
normal targets, set it IFF always_make_set is set.
