If a wiggle is needed due to white-space issues, it is good
to show them.
So in cases where that might be happening - unmatches space or
extraneous space - highlight spaces as inverse-video and tabs as
underlines.

vpatch: fix check_line to stop at hunk headers.
check_line() includes invisible bits because they could in some sense
be part of 'this' line. It ignore hunk headers, but it really should stop
at them, because nothing before could be related to this line.
This fixes a problem where 'N' and 'P' would find hunk headers

Top-right of the merge window identifies the current location in

Old code only allowed for a difference of three which didn't cope

Fix some new compiler warnings.
hi Neil, I pulled wiggle's latest head from git and tried to compile on Mac
OS X. I ran into some problems when I tried to compile with -O3 without
-ggdb.
gcc -Werror treated some uninitialized variable warnings as errors. Some of
the warnings look like real bugs, but many were false positives. Compiling
with -O3 and -ggdb makes all the warnings "go away." :)
I've attached a patch to fix the following valid warnings:

merge: make some conflicts less conflicting.
If a 'conflict' has an empty 'before' section, then it is probably
to separate things - and insertion in the original (unmatched) and
and insertion in the result.
So split it into those two, but leave the result marked as a Conflict
as the order of the insertions is not clear.
For now this mostly affects -B which can display the conflict
more effectively.

Browser: improve decision on when to split window for merger view.
Now that we are tracking in_conflict in the broswer we "know" when

Encourage more context into conflict reports.
Conflict reports currently don't contain much surrounding
'Extraneous' text. When the patch didn't really apply at all,
this context is very useful.
So encourage at least 3 lines of context from Extraneous or
Unchanged texts.
If it mostly comes from Unchanged text it isn't quite so useful,
so reduce the requirement.
Update self-tests to match. In most cases these are an improvement.
In a couple of case we maybe get a bit more context than really
necessary, but that is better than not enough.

Improve handling of hunk-header when merging.
If we are merging a patch, the patch will contain a number of
hunk-headers (essentially the @@ NN,MM @@) lines.
These should never appear in the merge, and must always line up with
end-of-line in the original as they represent a number of lines having
been deleted.
So:
Cause these to each create a simple Extraneous merger, never
combined with adjacent texts
exclude them from any conflicts in isolate_conflict, so they
can never appear in a merge
Ensure that a preceeding 'Unmatched' finishes on an end-of-line.
Also update lots of self tests with improved results.

Ensure that a hunk-header never appears in the middle of an Extraneous range.
A hunk header is always Extraneous. However Extraneous text before it is

to detect hunk headers and handle them better.
