b4833a2c62 rerere: Fix use of an empty strbuf.buf
The code incorrectly assumed that strbuf.buf is always an
allocated piece of memory that has NUL at offset strbuf.len.
That assumption does not hold for a freshly initialized empty
strbuf.

f1696ee398 Strbuf API extensions and fixes.
* Add strbuf_rtrim to remove trailing spaces.
  * Add strbuf_insert to insert data at a given position.
  * Off-by one fix in strbuf_addf: strbuf_avail() does not counts the final
    \0 so the overflow test for snprintf is the strict comparison. This is
    not critical as the growth mechanism chosen will always allocate _more_
    memory than asked, so the second test will not fail. It's some kind of
    miracle though.
  * Add size extension hints for strbuf_init and strbuf_read. If 0, default
    applies, else:
      + initial buffer has the given size for strbuf_init.
      + first growth checks it has at least this size rather than the
        default 8192.

52aaf649cb rerere: record resolution even if file is not in merge base
Two-file merges were rare enough that they were dropped outside of the
radar.  This fix is a trivial change to builtin-rerere.c::find_conflict().
It is still sane to insist that we do not do rerere for symlinks, and
require to have stages #2 and #3, but we can drop the requirement to have
stage #1. rerere does not use information from there anyway.

This fix is from Junio, together with two tests to verify that it works
as expected.

b4372ef136 Enable "git rerere" by the config variable rerere.enabled
Earlier, "git rerere" was enabled by creating the directory
.git/rr-cache.  That is definitely not in line with most other
features, which are enabled by a config variable.

So, check the config variable "rerere.enabled". If it is set
to "false" explicitely, do not activate rerere, even if
.git/rr-cache exists. This should help when you want to disable
rerere temporarily.

If "rerere.enabled" is not set at all, fall back to detection
of the directory .git/rr-cache.

[jc: with minimum tweaks]

30b250104d Future-proof source for changes in xdemitconf_t
The instances of xdemitconf_t were initialized member by member.
Instead, initialize them to all zero, so we do not have
to update those places each time we introduce a new member.

[jc: minimally fixed by getting rid of a new global]

a6080a0a44 War on whitespace
This uses "git-apply --whitespace=strip" to fix whitespace errors that have

still passes the test, and build result in Documentation/ area is unchanged.

599065a3bb prefixcmp(): fix-up mechanical conversion.
Previous step converted use of strncmp() with literal string
mechanically even when the result is only used as a boolean:

    if (!strncmp("foo", arg, 3)) ==> if (!(-prefixcmp(arg, "foo")))

This step manually cleans them up to read:

    if (!prefixcmp(arg, "foo"))

cc44c7655f Mechanical conversion to use prefixcmp()
This mechanically converts strncmp() to use prefixcmp(), but only when
the parameters match specific patterns, so that they can be verified
easily.  Leftover from this will be fixed in a separate step, including
idiotic conversions like

    if (!strncmp("foo", arg, 3))

  =>

    if (!(-prefixcmp(arg, "foo")))

This was done by using this script in px.perl

   #!/usr/bin/perl -i.bak -p
   if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) {
           s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|;
   }
   if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) {
           s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|;
   }

and running:

   $ git grep -l strncmp -- '*.c' | xargs perl px.perl

93822c2239 short i/o: fix calls to write to use xwrite or write_in_full
We have a number of badly checked write() calls.  Often we are
expecting write() to write exactly the size we requested or fail,
this fails to handle interrupts or short writes.  Switch to using
the new write_in_full().  Otherwise we at a minimum need to check
for EINTR and EAGAIN, where this is appropriate use xwrite().

Note, the changes to config handling are much larger and handled
in the next patch in the sequence.
