We stopped handling URIs such as "example.com:/some/p ath", because
this was confused with the Windows absolute path syntax of "c:/path".
Support absolute style scp URIs again, but only when the host name
is more than 2 characters long.

IndexDiff was extended to detect files which are both removed from the
index and untracked. Before this change these files were only added
to the removed collection.

Implementation delegates all work to the AddCommand class and,
therefore, supports only those options currently supported by the
AddCommand which means: --update and the filepattern... arguments.

The code analyzer can't know that passing a value known to be null is
not a problem. Hence better pass null explicitly instead of the
parameters being null.

There was a bug in ResolveMerger which is one reason for
bug 328841. If a merge was failing because of conflicts
deletions where not handled correctly. Files which have
to be deleted (because there was a non-conflicting deletion
coming in from THEIRS) are not deleted. In the
non-conflicting case we also forgot to delete the file but
in this case we explicitly checkout in the end these files
get deleted during that checkout.
This is fixed by handling incoming deletions explicitly.

The automatically generated commit message of a merge should have the
same structure as in C Git for consistency (as per git fmt-merge-msg).
Before this change:
merging refs/heads/a into refs/heads/master
After:
Merge branch 'a'
Plurals, "into" and joining by "," and "and" also work.

When --git-dir=X is given JGit creates a bare repository in the
directory X. However, when the --bare option is not explicitly
given, this is not properly reflected in the X/config file i.e.
the bare=true is missing. This change fixes this minor issue.

The JGit merge algorithm or the Merge Command may have problems with handling

JGit merge algorithm behaved differently from C Git when
we had adjacent modifications. If line 9 was modified by
OURS and line 10 by theirs then C Git will return a
conflict while JGit was seeing this as independent
modifications. This change is not only there to achieve
compatibility, but there where also some really wrong
merge results produced by JGit in the area of adjacent
modifications.

Introduced similar helper methods than in AbstractDiffTestCase.

When adding a new method near the end of the sequence we want to
show the full method inserted, and not tear the prior method due
to the common trailing curly brace being consumed as part of the
common end region of the sequences.

This test isn't that useful. The better way to evaluate diff
algorithm performance is to run `jgit debug-diff-algorithms` over
real-world repositories, such as linux-2.6.git. Whenever we modify
an algorithm we should manually verify that its runtime performance
doesn't get any worse than it already is.

HistogramDiff failed on cases where the initial element for the LCS
was actually very common (e.g. has 20 occurrences), and the first
element of the inserted region after the LCS was also common but
had fewer occurrences (e.g. 10), while the LCS also contained a
unique element (1 occurrence).
This happens often in Java source code. The initial element for
the LCS might be the empty line ("\n"), and the inserted but common
element might be "\t/**\n", with the LCS being a large span of
lines that contains unique method declarations. Even though "/**"
occurs less often than the empty line its not a better LCS if the
LCS we already have contains a unique element.
The logic in HistogramDiff would normally have worked fine, except I
tried to optimize scanning of B by making tryLongestCommonSequence
return the end of the region when there are matching elements
found in A. This allows us to skip over the current LCS region,
as it has already been examined, but caused us to fail to identify
an element that had a lower occurrence count within the region.
The solution used here is to trade space-for-time by keeping a
table of A positions to their occurrence counts. This allows the
matching logic to always use the smallest count for this region,
even if the smallest count doesn't appear on the initial element.
The new unit test testEdit_LcsContainsUnique() verifies this new
behavior works as expected.

Fixes the "Method ignores results of InputStream.read()" warning.
This is the only place where read() was used instead of readFully()
and the return value was not checked. So it was either an oversight
or should be documented. This change assumes it was an oversight.

As described in Bug 328551 there was a bug that the merge algorithm
was not always reporting conflicts when the same line was deleted
and modified. This problem was introduced during commit
0c017188b4 when reported conflicts have
been checked for common pre- and suffixes.
This was fixed here by better determining whether after stripping
off common prefixes and suffixes from a conflicting region there
is still some conflicting part left.
I also added a unit test to test this situation.

When creating a local branch based on another local branch, the
upstream configuration contains "." as origin and the source branch
as "merge". The PullCommand should support this by skipping the
fetch step altogether and use the base branch to merge with.
